====== Module "Ribbed slab" ======

{{ en:clt:hotspot:software:cltdesigner:manual:modul_tbeam:gesamtrippendecke.png?600 |Module Ribbed slab}}

===== Input data =====

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
==== General ====

{{page> en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_continuousbeam#general&inline&permalink&noheader}}

==== Structural system ====

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.

==== Cross section ====

The input of the CLT cross section is the same as for the [[en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_continuousbeam|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.

==== Loads ====

The input is the same as for the [[en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_continuousbeam|Module "CLT-Plate 1D - Continuous beam"]], but limited to distributed loads.

==== Fire ====

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

The input is the same as for the [[en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_continuousbeam|Module "CLT-Plate 1D - Continuous beam"]].

===== Results and Output =====

==== Cross section values ====

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.

{{ en:clt:hotspot:software:cltdesigner:manual:modul_tbeam:querschnittswerte_bsp_bsh.png |Stiffness values of the CLT plate as well as of the rib and the shear spring}}

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.

==== Summary of the results ====

The summary of the results is analogous to the [[en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_continuousbeam|Module "CLT-Plate 1D - Continuous beam"]].

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