Introduction
Check of Interaction shear and torsion consists of three checks:
- check of shear, "Shear check"
- check of torsion, "Torsion check"
- check of interaction of shear and torsion
All checks mentioned above are calculated according to clause 6.1 - 6.3 in EN 1992-1-1. The following preconditions are used for calculation :
- The checks are calculated for beams and columns and for general load (N+My+Mz)
- Cross-section with one polygon and one material is taken into account in version SCIA Engineer 15.
- The material of all reinforcement bars and stirrups have to be same in SCIA Engineer 15.
- The checks should be used only in case, that the angle between gradient of the strain plane and the resultant of shear forces is not greater than 15 °.
