4.1.1 Ultimate Limit State
Ultimate Limit State
In this dialog section, you can specify the calculation method according to which the shear stresses in the shear joint are determined. Both calculation types are described in chapter 2.1.4.
Plates on T-beams or box sections acting as compression or tension chords must be connected to the web by a shear-resisting connection. It must be verified that on the one hand the bearing capacity of the concrete compression strut is not exceeded, and on the other hand the tension strut force of the shear reinforcement can be absorbed. The theoretical basis for transferring shear forces between beam web and flanges is described in EN 1992-1-1, clause 6.2.4.
The Simplified method is preset for the design. In this method, only moments about the structural component's y-axis with the inner lever arm z = 0.9 ⋅ d are considered.
Alternatively, it is possible to determine the longitudinal force difference by a General integration of stresses in single cross-section parts. However, this option requires more calculation time. The procedure is described in chapter 2.1.4.
