Graphial display of nonlinearly calculated crack widths in rfem. However, an rstab license is not required for using dlubal composite beam standalone operation is possible. Reinforced concrete design with dlubal software dlubal software. For reinforcing steel, we can roughly assume this fact until yielding is reached anyway. With rstab you can easily and quickly define a structural model and then calculate the internal forces, deformations, and support reactions. Crack width analysis with optional increase of the required reinforcement in. Structural analysis software rstab and concrete addon module for design of. The software is fully activated and can be used without any restrictions. We can justify this approach by the fact that the ratio of stress to strain for concrete behaves nearly linearly up to a stress of. In the addon module rf concrete surfaces, is it possible to limit crack widths due to internal.
