Model
A ceiling system is calculated as a continuous beam. This example is described in the textbook [1], Chapter 11.2 "Floor as Two-Span Beam".
The span is 4.5 m in the first bay and 5.2 m in the second bay.
Constant surface loads of 2 kN/m2 in load case 1 and 2.5 kN/m2 in load case 2 are applied. In order to keep the dead weight identical to the literature example, an additional weight of 1.21 kN/m2 is applied in load case 1.
It is calculated on the effective 1 m wide cross-sectional strip. The support is carried out with linear supports in uZ immovable on all three supports. The middle support is also immovable in uX. Furthermore, a nodal support is arranged there in the Y-direction so that the system does not become kinematic.
plate element
The structure of the plate element is BSP L7s2 (30l - 30l - 30w - 40l - 30w - 30l - 30l)
This results in the following stiffness:
The calculation of the stiffness is explained in chapter Stiffnesses for multilayer surfaces .
