When determining internal forces, you can choose between calculation method 1 (uncracked over entire beam length) and calculation method 2 (crack formation over internal columns).
In both cases, it is possible to consider a constant effective width of the concrete slab over the entire span according to ENV 1994-1-1, 4.2.2.1 (1) and a redistribution of the moments. Internal forces for the design of shear connectors can only be determined by the elastic calculation of internal forces using the RSTAB analysis core (no RSTAB license is required).
The calculation performs fully automatic determination of the effective cross-section properties at the respective points of time, considering creep and shrinkage. In the RSTAB user interface, the structural models are created as a member structure, including all boundary conditions and loading. This way, reliable calculation of the internal forces with the effective cross-section properties is ensured.
