We are pleased to introduce a powerful building component design suite that meets day to day requirements of practicing engineers. The robust building component design software from S-Frame not only perform instantaneous code checks but also speedup the design process with AutoDesign capabilities. 



Design and Detail Reinforced Concrete Walls, Columns and Beams

Quickly design and detail reinforced-concrete column, beam and wall sections to multiple design codes with S-CONCRETE, the concrete design software of choice by structural engineers worldwide.

Optimize a single section design or evaluate thousands of concrete sections at once.


Watch S-Concrete in Action

See automatic and immediate results as design parameter change.
Comprehensive code checks go well beyond the strength of the concrete section: Design for axial, shear, moment loads, and torsion.No black-box solution: results include everything you need to quickly detail and optimize concrete walls, columns and beam.

  • governing load cases
  • detailing checks status
  • intermediate results
  • errors & warnings for failed checks with clause references

S-CONCRETE Wall, Column and Beam configurations

Concrete Wall Design

Design and detail walls having Rectangular-shaped, I-shaped, C-shaped, L-shaped and T-shaped sections.

In addition to distributed panel reinforcement, the boundary (zone) concentrated reinforcement can be specified for each of the various sections.

Concrete Column Design

Design and detail rectangular or circular columns, with rectangular or circular ties or spiral reinforcement, rectangular or circular holes, and steel I-shaped composite columns.

S-CONCRETE columns

Concrete Beam Design

Design Rectangular beams, T-beams, L-beams, or Slab bands, with closed or open multi-leg stirrups.


Integrated Solutions with S-FRAME Analysis and 3rd Party Software

    • S-FRAME Analysis supports reinforced concrete design with the Integrated Concrete Design (ICD) option. With ICD engineers can build, analyze and edit concrete structures, run code checks, perform design group optimizations and automatically generate detailed design reports. Load data is automatically applied to concrete sections after running an analysis. Design and detail the sections within the S-FRAME Analysis Environment for maximum productivity.
    • S-CONCRETE Batch Processing Mode performs the design of thousands of concrete beams, columns and walls while performing structural analysis using any 3rd party analysis software.
    • Alternatively copy and paste loading data from any 3rd party application, using the interactive S-CONCRETE design interface. Apply factored loads for walls, columns and beam sections. S-CONCRETE supports Axial (Tension or Compression), Shear and Moment in two directions and Torsion loading.
    • S-CONCRETE Basic is a concrete design and detailing plug-in for Adapt Builder


Easily Define Concrete Sections

Quickly and easily specify concrete section dimensions, concrete and steel reinforcing strengths, concrete cover, reinforcement bar type, units and design codes and reinforcing bar type within a single dialog box.

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.

Design Codes Supported

  • ACI 318-14, 11, 08, 05, 02
  • CSA A23.3-14, 04
  • EN 1992-1-1:2004  with standard design values
  • EN 1992-1-1:2004  with UK National Annex
  • BS 8110:1997
  • CP 65:1999


S-CONCRETE displays immediate design results in the Visual Editor window, identifying hot-spots (problem areas) so the engineer can efficiently change model parameters within the same window.
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.

Once the design is complete, the ability to export the cross section with reinforcing steel to an AutoCAD DXF file showing the actual reinforcement layout, including primary and secondary bars, ties and stirrups, allows for quick and easy incorporation into engineering drawings.

S-CONCRETE’s comprehensive and customizable report provides details on all code checks performed.
Reports include:

  • Summary of results
  • Section dimensions and reinforcement layout
  • Calculated section properties
  • Calculated design loads
  • Utilization (demand/capacity) ratios
  • Status of checks (not applicable, acceptable, warning, unacceptable)
  • Governing load cases

Steel Member Design Code Assessment

Use S-PAD to quickly code check a structural steel column, beam or brace without modeling the entire structure. Simply input design loads and effective lengths of the steel member then run a quick check in seconds, or even better, run an auto-design to identify the optimum section.

S-PAD includes advanced code checking capabilities as well as auto-design to the same steel design codes supported by S-STEEL, for both strength and serviceability. This standalone application employs a simple spreadsheet-like interface that delivers powerful steel-design and code check capabilities.

Design Interface

S-PAD uses a simple, intuitive spreadsheet layout that allows up to 20 design cases to be evaluated simultaneously.
Member definition input can be copied in from CSV files.
Input files can be saved and can contain multiple worksheets each with up to 20 design cases.

Easily view detailed design calculations for all section shapes.

Support for American, Canadian, British, European and other international section sizes.


Design Results

S-PAD features exactly the same comprehensive design output as S-STEEL as well as the same set of design constraints giving the engineer full control of all design parameters.
Quickly and easily input strength and stability design forces, effective lengths in compression and unsupported lengths in bending steel elements (beam, column or brace) and run a quick code check.

Auto-design steel members to help identify an optimum section according to:

  • Least weight
  • cost
  • depth and surface area

Steel member auto-design generates a sorted list of adequate sections to identify optimum sections easily. Detailed design calculations can be viewed for all sections.
Code relaxation option is available for more conservative designs.
