COMOSYS Features

Structural Analysis & Design

Structural Analysis
COMOSYS is a general-purpose structural analysis, design, and detailing software that integrates modeling, analysis and design, detailing, and drafting phases in a single environment. All kinds of structures with arbitrary complexity can be modeled using advanced modeling capabilities of COMOSYS. A powerful finite element engine working behind the scenes ensures exact results while structural steel members can be designed according to American, European, and Turkish codes.


Watch Analysis and Design features of COMOSYS




COMOSYS provides the user with the ability to design steel structures in accordance with many international design codes. These include the Turkish code, both the American Allowable stress design code AISC-ASD, the Load Resistance Factor Design code AISC-LRFD, the EuroCode EC3 etc.



Steel Modeling and Detailing

COMOSYS Steel Detailer is a general-purpose modeling software for steel structures. COMOSYS Steel Detailer allows you to model structures ranging from roof trusses to most complex industrial structures, from silos to power plants, pipe racks to multi-storey buildings down to the tiniest details in 3D. Shop and part drawings, material take off tables are generated automatically by the COMOSYS.

With COMOSYS you are not limited to structures which fit a certain template. Whether you are in the housing business, or you design industrial plants, complicated plate work, skyscrapers or even bridges, you will be pleasantly surprised that COMOSYS never lags and is always there to provide the necessary framework needed to facilitate your work. You can even develop your own specialized macros or ask us to do it for you which will give you the edge over all your competitors.

Concrete Modeling and Detailing

Formwork and Rebar modeling is a unique challenge in itself. While steel modeling is complicated in its own right, the modeling of industrial plants in concrete with their non-building like geometries along with the placement of 3D rebar in these complex shapes requires a novel approach. Many programs claim to be successful, but COMOSYS delivers the goods. Several state-of-the-art technologies have gone into the preparation of these modules, and we invite the user to spend a few minutes reading about them. Thoroughly integrated with the rest of COMOSYS these two modules will once again save you man hours and win you prestige with their beautiful drawings and detailed models.


Watch 3D Rebar Modeling features of COMOSYS




Drawing Module

COMOSYS comes with a very powerful standalone drawing module. While COMOSYS automatically produces many types of drawings, it also provides tools that significantly reduce the amount of time necessary for the drawings that have to be produced manually. As a bonus of 3D modeling, material take-off tables are immediately ready and the user can create sections at any point or views from any point of view. In addition to this, for editing and revising drawings, no other general purpose CAD program is required because COMOSYS provides all the tools necessary for editing 2D drawings.

COMOSYS offers a completely standalone drawing module which doesn’t require the user to install any AutoCAD or Microstation for it to work. Thus, a major portion of the CAD related investment is saved making the cost benefit ratio of investing in COMOSYS even more attractive.



Tank Modeling
COMOSYS Tank Design module is built on general purpose structure of COMOSYS but provides specialized commands for modeling of tanks. COMOSYS Tank Design module can increase the productivity of the user by a significant amount. You will find that the after setting up the system you will be able to detail tanks which normally took up to a week to detail in a matter of hours. These savings in man-hours translate into profits while also giving the user a lot of space to accommodate minor revisions.



COMOSYS Distinctive Features



COMOSYS provides an extensive steel connection library which can work with or without analysis results. If no analysis results are available, the user can choose to design the connection according to a certain percentage of the capacity of the section or if analysis results are available these can be used directly. Some of the main connections available are listed below.
Some of the main connection types are:

• Beam to Beam simple connections
• Beam to Beam fixed connections
• Beam to Beam seating connections
• Beam to Column simple connections
• Beam to Column fixed connections
• Beam to Column seating connections
• Column on Column seating connections
• Base plate connections
• Vertical bracing connections
• Horizontal bracing connections
• Purlin and Girt connections
• Wind column connections
• Splice connections
• Truss connections
• Truss seating connections
• Crane Girder connections
• Monorail connections
• Sag Rod connections
• Stair and ladder connections
• Handrail modeling
• Grating & Chequered plate modeling



Clash Checking is fully integrated with the basic work environment of COMOSYS. Find out about possible clashes before the person at site gives you a call to tell you about it. This will not only save valuable design man-hours but also reduce the problems for the construction team. COMOSYS will not only provide you with clash reports within a discipline but also give inter-disciplinary clash reports. These reports also allow the user to zoom in to the objects which are clashing and manage the clashes. Many a times you get a model from somewhere which you need to incorporate into your own to see any possible clashes. But to your horror you find that the model which has been sent to you has its own internal clashes as well which clutter up your clash reports. COMOSYS allows you to overlook these clashes and focus entirely on where the other discipline is clashing with yours.



Companies will be able to save a considerable amount of time & money using this unique feature of COMOSYS. Typically during the analysis stage the engineer is not concerned about the exact placement of members according to detailing requirements. In particular trusses aren’t modeled according to the centre of gravity of the profiles, horizontal bracings aren’t located at their correct elevations and with the right orientations and the girts and purlins aren’t modeled in their actual positions. Splice Positions are not really a consideration and similarly other such factors which don’t affect the analysis are left for the detailer to worry about. However, this also means that the model prepared by the Engineer is not directly usable and needs a lot of remodeling. The unique AUTO ADJUST technology present in COMOSYS provides practical and useful solutions to many of these problems and with a press of a single button the ugly analysis model is converted into a model ready for detailing!



Follow the advantage created by AUTO ADJUST with IntelliConnect. This unique feature of COMOSYS will help hat many simple connections and some advanced ones like floor beams with horizontal bracing spanning into them are handled easily leaving the modeler with only the complicated areas to deal with.  IntelliConnect will connect your girts and purlins, most of your trusses, floor beams with and without horizontal bracing and even put the batten plates in all your twin profiles automatically with a single click. Simple vertical bracing connections too will be handled. The intelligence of this feature has been made customizable to a large extent. Try it and save time. Whenever it will work it will save you precious man-hours.




Intelliclone is another revolutionary advanced command which is one step beyond Intelliconnect. Intelliconnect and Intellliclone are like sister commands, and they work together hand in hand. Intelliconnect is working in the cases where the pre-programmed template-based Intelligence inside COMOSYS. Wherever the connections made by Intelliconnect needs to be shifted to some other parent frames or some other locations in the model with similar situations, there we can use the more revolutionary Intelliclone command. It offers a very similar solution like Intelliconnect, but this time the user is the one who directs the modeling. If the user models only one joint, Intelliclone allows the user to truly propagate and clone that joint without any clashes to wherever location needed in the model

MkaPEB is the most comprehensive and user-friendly software developed to help the Engineers and EPC contractors to quickly produce various alternatives and cost estimates for PEB structures.

Why MkaPEB?

  • Specialized software for single storey PEB Structures. 
  • Most easy to use and quickly compare cost effective structure configurations using extensive model wizards.
  • Once you finalize the  structure, apply loads and design the structure including foundations according to major design codes.
  • After completion of the design, build your  Real 3D Solid Model of the structure including Steel connections, Crane beams, Baseplate & foundations
  • Produce cost estimation report and detailed design calculations
  • Produce  GA drawings, Assembly drawings and Part drawings
  • Produce files required to send to CNC machine


Watch how MkaPEB offers complete solution for PEB structures







MkaPEB has a wide range of template types defined for portal frame and steel roof truss systems with variable cross-section. All the features of the roof systems in these templates are parametric. If needed, they can be defined side by side and in different levels.







Recognisıng the building structure and understandıng the regional snow loads within the areas where snow accumulates on the roof, dependent on the load standards selected by the user.

It automatically loads varying loads according to the regions where the roof purlins are located.

When an engineer makes a change in the dimensions and shape of the structure, the most time-consuming load analysis is done in less than 1 second.



Wind loads are the most complex of loads acting on the structure. The value of the load on the roof and facades varies regionally.

MkaPEB  is familiar with the structure and knows the Eurocode, ASCE-07, IS-875 standards, automatically performs this complex calculation when the structure properties change.

The calculation which has been made by the software automatically transferred to the roof and facade purlins and the main carrier system.



For overhead crane loads, the overhead crane runway beam should be designed first. MkaPEB calculates this according to the rules given in AISC-Design Guide 7 and EN-1991-3 and automatically assigns loads to the columns.



 TDY-2018, AISC-341-16, Eurocode-8, EAK-2000 (Greece), IS 1893 Earthquake regulations are implemented in MkaPEB.




Elements on roofs and facades, especially central braces, buckle under compression loads due to their slenderness. MkaPEB can identify which element will buckle under which load and analyzes the system so that it is only supported by the tension only members. Whilst making this analysis, it takes into account the thermal effects of Summer-Winter temperature differences and wind and earthquake loads coming from the facade. After solving each one separately, it superposes and controls the element strengths according to this last situation.

By doing this, MkaPEB was able to use tension only rods in the braces.



 Detailed design will be carried out according to various international codes.






MkaPEB steel truss automatically performs joint calculations for many joints on roofs and facades.

It resizes the connection plates according to the welding lengths calculated in the steel shears. Thus, the processing time is shortened and the possibility of error is eliminated.

If the selected steel structure design regulation is AISC-360, Connections is  based AISC-360-16 and design guides published by AISC.

If Eurocode 3 is selected, the strength of the connections is checked based on EN-1993-1-8.

The design of other combinations can be done after static calculations are made from the combination design page.

The properties of the combination can be changed parametrically.

The distances of the bolts to the edges and the limits of the welds are checked.

While calculating the strength of the connection, the changes can be followed on the 3D model.

2D technical drawing of the connection can also be taken.



 In our single-storey warehouse-hangar type structure, the columns are under the effect of one-way bending. Especially when calculating foundations in structures with overhead cranes or under the influence of high wind force – Soil capacity It is thought that geotechnical controls should be done in addition to the reinforcement calculation.

The general bearing capacity formula recommended by Hansen Vesic in Eurocode -7 is used. Our aim with MkaPEB is to make all the elements of the steel structure, from the roof to the timeline, resistant to disaster situations.



 Today, many structure analysis software gives its calculations within tables. And they show the accuracy of their calculations with verification solutions. This view was not adopted in MkaPEB. For this reason, the load calculations are given with detailed calculation reports for the design of steel structure elements and connections. The engineer can follow the reference, formulas and process steps of the calculation.



 We came to the first question asked by the engineer or the investor who prepared the proposal or made the analysis. What is the cost of this structure we calculated? 

MkaPEB can extract all the material list used in the building.The user can change the unit prices of the materials.Amended new unit prices are saved for future projects.Prices can be updated automatically according to the daily changing exchange rates. The ratio of scrap quantities for the offer can be changed from the table.On the table, the total used steel, m2 used steel, m2 unit cost, total cost can be examined.



MkaPEB prepares 3D solid model along with connections, which practically represent real life structure.




Today, CNC machines are widely used in the manufacture of steel structures. The biggest feature of 3D modeling software such as Tekla, Advance Steel, Bocad, SDS/2 is that it can produce DSTV-NC files. This issue was primarily targeted when MkaPEB was started to be developed















A- PEB (Pre-Engineered Building) type structures

Variable H section frames are 25% lighter than gantry frames made of normal rolled steel. This ratio increases as the frame opening increases.

Automated Design

Estimate your section dimensions, reinforcement amounts, and configuration then let the S-CONCRETE Automated Design tool check and modify your section in an iterative, automatic process that arrives at an optimum configuration for the section, while satisfies design requirements.

Use the S-CONCRETE Visual Editor to fine-tune your section design.  Main design parameters along with principal code check results are efficiently displayed on a single graphical window for easy reference.  Change and control your design parameters directly in a single window, getting immediate feedback as changes are made.

Steel Reinforcement Tools allow users to select and control easily:

  • Vertical and horizontal reinforcement including bar size and count or spacing.
  • Multiple layers of vertical bars in columns or longitudinal bars in beams.
  • Zones for concentrated vertical reinforcement in walls.
  • Tie and stirrup configuration, bars size, spacing, and hook type.
  • Splice type of vertical reinforcement, which is taken into consideration by S-CONCRETE in bar spacing checks.

S-CONCRETE design options

Automatically generate required tie arrangements for column, wall and beam sections.
All of the column designs shown below are automatically generated by simply increasing the vertical bars in the section.

Users can control the interactive iterations that check and update the design within the Visual Editor window.

Review Warnings Related to Code Checks

S-CONCRETE comprehensive code checking goes well beyond the strength of the concrete section.

In the example shown, the section capacity for applied Axial, Flexure, and Shear forces are well within limits, however, the detailed checks for tie size and tie spacing, and clear spacing between bars (at the bar splice location), do not meet the code requirements. S-CONCRETE gives a color-coded Warning to the user .

Warning messages are readily identified with citations of the specific Code Clauses as shown at the right.

concrete design report

S-CONCRETE generates and displays axial force versus biaxial moment interaction envelopes, N-M (P-M) diagrams. These envelopes are used to provide information for the relevant checks performed by the program. The diagrams are automatically generated for all applied moment angles, Theta, that are part of the specified load cases, as well as the four right angles of the section, i.e. 0, 90, 180, 270 degrees.

K3-Tent tensile membrane structures design software

K3-Tent is a software suite intended for designing tent structures. The software helps speed up the compilation of design documentation and improve the quality of manufacturing order preparation for any tent structure shape. The K3-Tent suite provides highly visual and effective tools for designers to work with surfaces of any complexity. In addition, K3-Tent significantly reduces the time required for finding the shape of the envelope, visualizing the final structure, marking a cutting line, and unfolding pieces. The K3-Tent suite is a further development of the FABRIC CAD System.


k3-Tent Software in action


How K3-Tent Software Can help you? 






K3-Tent Software Operating Principle

The K3-Tent Suite provides the ability to draw up architecture, construction, and manufacturing documents required to make tent structures of any complexity. K3-Tent software simulates the shape of a “soap film” surface for a specific frame. K3-Tent software simulates a soap film surface shape for a specific frame when retrieving it from the soap solution. The frame may be composed of rigid or stretchable (rubber) ribs.

  • The designer creates a frame consisting of straight sections and arcs.
  • The designer sets the frame rib boundary conditions (loose, hold fixed, fixed length, etc.).
  • The designer specifies if a facet should or should not be used in creating a surface.
  • The software automatically calculates the shape of the envelope.
  • The designer checks the correctness of the shape by using an isoline plotting tool and a heat normal map.
  • The designer marks cutting lines on the envelope.
  • The software automatically cuts the envelope into pieces and unfolds the pieces.
  • The software can be used to export unfolded pieces to .dxf format.



Designing tent structures with the K3-Tent Software consists of three stages


To create a tent structure, the system uses a special object called Frame. A frame is a set of interlinked spatial lines. These lines are straight sections and/or arcs. A frame is a template for the future tent structure. Frame nodes shall correspond to the awning cloth fastening points. Closed topological triangles or squares of the frame are automatically perceived by the system as cloth pieces. Therefore, the designer must make sure that there are no triangles or squares on sections of the structure not to be covered with cloth. The designer’s task is to create a frame. The system automatically finds the cloth surface. The implemented algorithm ensures that the cloth surface has no “bubbles,” folds, etc.


Creating the cutting pattern for the designed awning cloth is one of the most important and critical stages of the design. The cutting pattern means dividing the awning cloth into individual pieces and then generating a flat pattern for each cloth patch. When dividing the cloth into patches, it should be kept in mind that each patch is a part of the surface with double curvature, which cannot usually be unfolded precisely. We call this unfolding procedure “2D mapping,” and it can only be done approximately. The less the cloth circuit’s Gaussian curvature, the higher the accuracy of the 2D mapping. Normally, 2D mapping allows patterns to be generated with linear sizes 1%–2% lower than that of corresponding lines on a curved surface. Therefore, a suitable tolerance must be applied for the cutting pattern. The designer plots mark lines and cutting lines (future seams) on the created 3D model of the awning. Several different line plotting algorithms are implemented in this version of the system, including an algorithm for plotting the shortest path between two arbitrary points.


The K3-Tent suite allows the designer to automatically generate cutting patterns for fabric cloth patches. The designer only needs to specify the required piece or select all pieces of a cloth. The cutting pattern can be exported to .dxf format for future use.


The design process with K3-Tent system can be conventionally subdivided into 6 steps:


1 .Creation of the Frame object on the basis of set of spatial straight lines and circle arcs which defines links and tent constrains.

2. Definition of boundary conditions for the Frame edges and nodes
3. Creation the surface of the tent by the system automatically.
4. Tracing cutting lines on the surface of cloth. The system cuts the tent surface to patches automatically.
5. Development patches pattern by the system automatically
6.Fabric patterning, cutting, welding and tent surface assemblage


Components of the K3-Tent Software Suite

The K3-Tent software suite has a modular structure enabling the individual compilation of each work place depending on its purpose. The K3-Tent software suite includes the following components:
