Standards-based verification example

Im nachfolgenden Beispiel wird die gesamte aufzunehmende Querkraft als Durchstanzkraft VEd an einem Stahlbetonwandende ermittelt. Die Durchstanzlast entsteht durch die flächige Belastung von 10 kN/m² einer Stahlbetondecke mit der Stärke von 30 cm. Die Geometrie der Deckenplatte mit vier freien Rändern ist in dargestellt. Anhand dieses Beispiels soll überprüft werden, wie weit die Ergebnisse der unterschiedlichen Softwares von dem händischen Ergebnis nach der Norm DIN EN 1992-1-1/NA:2013-04 entfernt liegen.

Below, we have calculated the natural frequency of a two-hinged frame. It is 5 m wide, 3 m high and has a strength class of C 30/37. The posts have dimensions b/h = 26/26 cm and the transom has dimensions b/h = 30/30 cm. The density is 2500 kg/m³.The calculations are carried out using the ‘Lanczos method’ and without mass-proportional or stiffness-proportional damping. Furthermore, the quadrilateral elements were generated using the mesh generator and linear spline functions were employed.Both the first symmetric and the first asymmetric natural frequencies are output.

In the following example, the moment and shear force distributions of a uniaxially stressed solid slab spanning two spans are determined. A freely rotating support is assumed. The loads consist of the dead load gd = 8.5\,\mathrm{kN/m^2} and a live load qd = 7.5\,\mathrm{kN/m^2} acting across each span.The internal forces are calculated for 3 different load combinations:LC1: gd + (qd in spans 1 and 2)LC2: gd + (qd in bay 1)LC3: gd + (qd in bay 2)A span of 5 m and 4 m is assumed for the two fields respectively. The slab thickness is 0.19 m. The geometry of the solid slab is shown in the…

Numerical verification example

When determining the stresses and strains in a glass plate, two different results are obtained depending on whether linear or non-linear plate theory is used. This is due to the strains being relatively large in relation to the plate thickness. The validity of linear plate theory is therefore lost. Diaphragm forces arise within the plate, which have a favourable effect on the stresses and strains.This example is intended to verify whether the software programmes used are capable of determining the maximum principal tensile stress and deflection at the centre of a glass plate in accordance with…
