|BETONexpress, software for designing structural elements of reinforced concrete.|
|With BETONexpress you can easily design structural elements of reinforced concrete. For each structural element, you specify the basic dimensions, loads and material properties, and you obtain the detailed concrete design in ultimate limit state (ULS), and in serviceability limit state (SLS).
The dimensioning is according to Eurocode 2, EN 1992-1-1:2004, Design of concrete structures, General rules and rules for buildings, with supplement of Eurocode 7, EN 1997-1:2004, Geotechnical design – General rules, for geotechnical analysis (footings, retaining walls), Eurocode 0, EN 1990:2002, for load combinations, and Eurocode 8 for seismic loading. The last EN versions of the Eurocodes are implemented. You can also compute the capacity of slabs, beams and columns strengthened with FRP (fibre-reinforced polymers). Regular and light weight aggregate concrete included.
|The program’s CAD modulus automatic generates detailed drawings of the structure and the reinforcement. A combined detailed report and reinforcing steel schedule is produced for the designed concrete components. Assumptions and references to design codes are shown in the report. The reinforcing steel schedule can be edited with a specialised editor which is included. The user can select the applicable National Annex. The design code parameters, as well as default values, can be adjusted by the user. Design Charts and Tables for use and understanding of Eurocode 2 are included n the program. In addition a set of engineering tools are included in the program.|
Solid slabs and ribbed slabs.
The basis for the design of foundations is the bearing resistance of the soil.
The design bearing resistance can be calculated using analytical or semi-empirical methods. Annex D of Eurocode 7, EN1997:2004 describes a method of obtaining the design bearing strength of the soil.
Vertical loading and moments at the top. Dead and live loading.
Exact computation of pressure distribution under the footing. Geotechnical design using Eurocode 7, EN 1997-1:2004, or allowable soil stress.
Load combinations according to Eurocode 7 (EQU, STR, GEO load cases), and Eurocode 0.

Fundaments of Steel columns (2015)
The concrete footing of steel structures has to be designed to resist soil pressure for maximum vertical load and it must have enough weight to resist uplift from wind or seismic forces. You can design Pin and Fixed end column foundations. You can also specify if the foundation has a horizontal tie to take the horizontal outwards forces or not.
Loading on the fundament
The final actions after multiplication with safety factors (γG and γQ) Eurocode-1990-1-1, Table A1.2
For downwards loading usual values are: γG =1.35 (unfavourable), γQ=1.50.
For upwards (uplift) loading usual values are: γG =0.90 (favourable), γQ=0.00.
Steel Tie and Passive earth pressure
The high horizontal forces acting at the base are acting outwards as a result of bending in the columns due to vertical loading on the roof. This is resisted in two ways.
Retaining walls of gravity or cantilever type (reinforced). Geotechnical design using Eurocode 7, EN 1997-1:2004, Geotechnical design – General rules or allowable soil stress. Active and passive earth pressure using Coulomb’s theory. Design of gravity walls using Eurocode 6 (EC6) or allowable stresses.
Earthquake analysis according to Eurocode 8 (EC8), Mononobe-Okabe.
Two different types of cantilever walls in the program:
The design of cantilever type walls is based on Ultimate Limit State Design of concrete according to Eurocode 2. The design checks are performed at each tenth of the stem height. The reinforcement of the stem is optimised, and depending on the stem height the reinforcement is reduced toward the top of the wall. The reinforcing bars are automatically placed in the reinforcing bar schedules. Optional Base key against sliding.
Load combinations according to Eurocode 2, Eurocode 7, (EQU, STR, GEO load cases) and Eurocode 0.

Water basins, swimming pools (2015)Design of rectangular water basins. The solution is for a 2-dimensional cross section across the smallest dimension (width) of the basin.
The basin is assumed to sit on elastic ground and is analyzed with finite element analysis. The basin walls are subdivided in 2 beam elements of length H/2.The basin floor is modelled with 16 beam elements with nodal points connected to the ground with elastic springs. The stiffness of the elastic springs is computed from the Winkler’s foundation modulus Ks [kN/m2/m].The loading conditions include all the load cases according to Eurocode 0 (EQU, STR and GEO) for:· Empty water basin (only earth pressure)
· Filled water basin without earth pressure
· Filled water basin with earth pressureThe reinforced concrete design includes also serviceability control with limit crack width specified by the user.
Basement walls (2015)· Walls with only the bottom restrained for lateral movement.
· Walls with restrained the bottom and the top for lateral movement.In the first case the sliding of the wall is prevented due to the retraining of the base in movement. The active earth pressure is computed as usual using Coulomb’s (1776) or Rankine’s (1857) theory, Eurocode 7 § 9.5.1.In the second case, the active earth pressure conditions are obtained for Ko in rest conditions according to Jaky (1948), Eurocode 7 § 9.5.2.
Basement walls (2015)Bearing walls in vertical or horizontal load on the top without any earth pressure.
The horizontal load on the top can be defined from Eurocode 1-1-1:2001 Table 6.12 according to National Annexes.
The horizontal load on the top can be also defined according to Eurocode 1-1-7:2006, in case of impact load.
Walls with horizontal distributed load (2015)In case of wind loading the wind pressure is according to Eurocode 1-1-4:2005.
Corbels – Brackets
Short cantilevers projecting from column faces, with ac/hc<=1, where ac the load lever arm and hc the corbel height. Design according to Eurocode 2, § 5.6.4,§ 6.5, and Annex J.3. Load combinations according to Eurocode 2 and Eurocode 1.

Deep beams with dimensions Leff/h<=2, where Leff length and h height.
Design according to Eurocode 2, § 5.6.4,§ 6.5, using simple strut and tie model. You can design deep beams subjected to uniformly distributed load (with dead and live components) at the top and bottom faces of the beam.
