The InfoCAD program system can be used to conduct ultimate limit state and serviceability checks for any 2D and 3D loaded beam or shell structure. Elements with no prestress as well as prestressed elements with subsequent bond, without bond, with external prestressing and in mixed construction can be analyzed.

The following calculation options exist for all structural parts according to the SIA standards:

  • Definition and combination of the actions
  • Bending, shear and torsional design
  • Prestressing with and without bond
  • Fatigue checks
  • Punching shear check
  • Checks in the serviceability limit states
  • Crack width limitation
  • Nonlinear calculations in state II
  • Earthquake check using the response spectrum method

All structure types can be handled with equal ease, from a simple floor slab to a geometrically complex prismatic shell structure or solid model.

When using the predefined material types according to SIA (C12/15-C50/60, LC12-LC50/55 as well as free concrete material, for instance for high-quality concretes), the program offers the corresponding design specifications and actions. All partial safety factors and combination coefficients are automatically set according to the structure type.

The program combines the input and carries out reinforced concrete bending and shearing design for the design situations specified.

Combined support forces are available for the interactive punching shear check.

Depending on the requirement (for instance, moveable frame or tunnel section) a nonlinear calculation taking into account the cracked section can be carried out. The calculation is performed either for the ultimate limit state or the serviceability limit state.

The check according to the response spectrum method allows you to plan structures that take into consideration the effects of earthquakes.
