D1.1Task descriptionHere is the problem from the DBV collection of examples [1], Example 4: Based on a point-supported slab. The slab internal forces and the required longitudinal reinforcement are covered in EvaDAT Example 0036. For this reason, a detailed problem statement and a repeat of the boundary conditions for the FEM analysis are omitted here; please refer to Example 0036 in this regard: In this example, the punching point on the B/2 axis is examined.The punching shear analysis is carried out, on the one hand, using the load calculated manually from the load application areas from [1]…

Fig. A1-1gk1 = 10.0 kN/m²qk1 = 7.5 kN/m² OfficeQk2 = 5.0 kN/m snowFor the system shown above, the stability analysis is to be carried out and the support moment at the ultimate limit state above column B is to be determined. The load combination is to be carried out in accordance with the standard, taking into account the partial safety factors and combination factors.

Analytical verification example

The system consists of a circular plate with a radius of 5 m and a constant surface load. The plate is hinged at the edge (u-z = fixed, all other degrees of freedom are free) and is analysed as a plane problem with three degrees of freedom (phi-x, phi-y and u-z) per FEA node. For the reference solution, the results of the deflections with and without a shear component, as well as the bending moment, are given for various plate thicknesses at the centre of the plate. This example can be used to check whether the elements employed in the relevant software are capable of correctly modelling the…

D1.1 Problem StatementA square block foundation for precast reinforced concrete columns is to be designed. The recess in the block foundation is formed using a rough (serrated) formwork surface. The design shall be carried out in accordance with DIN EN 1992-1-1/NA 1.5.2.5 and 1.5.2.6 for loads typical of building construction, which are to be assumed as predominantly static loads.Based on a site investigation report, the following conditions are to be assumed: non-cohesive subsoil, aggressive to concrete, frost-free. Two load cases are derived from the column design:Edge column: uniaxial…
