Module "Ribbed slab"

The input is divided into:

• general information about the project and the considered structural element
• definitions of the structural system
• definitions of the cross section
• input of the loads
• informations about vibration parameters
• calculation options

In this release, only single span girder can be calculated. The supporting width and span (via x-value in the table) can be defined within this input field.

The input of the CLT cross section is the same as for the Module "CLT-Plate 1D - Continuous beam".

Die Definition des Rippenquerschnittes (Rechteckquerschnitt aus BSH oder Vollholz) erfolgt über die Eingabe der Höhe und Breite der Rippe sowie Auswahl des Materials.

The input is the same as for the Module "CLT-Plate 1D - Continuous beam", but limited to distributed loads.

Show description

In this module, currently no structural fire design is possible.

The input is the same as for the Module "CLT-Plate 1D - Continuous beam".

Show description

The stiffness values of the CLT-plate and the GLT-beam as well as the shear spring, which are shown in the upper section of the tab "cross-section values" are parameters for the determination of the effective width.

Underneath, the effective width, the center of gravity as well as the bending and shear stiffness of the T-beam at the supports and in between are shown.

The summary of the results is analogous to the Module "CLT-Plate 1D - Continuous beam".

Show description

However, there are differences for ULS - shear, since for the CLT-flange also the in-plane shear has to be considered.
