===== 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 ====

==== 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 (plate cross section) is the same as for the other Module. However, you can still select whether the plate is at the top or bottom.

The rib cross-section (rectangular cross-section made of glulam or solid wood) is defined by entering the height and width of the rib and selecting the material. If "Standard dimensions only" is selected, the dimensions for the nearest standard cross-section are set.

==== Loads ====

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

==== Fire ====

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

==== Vibrations ====

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

==== Cross section values ====

On the tab "cross-section values", 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 button {{:clt:hotspot:software:cltdesigner:manual:modul_tbeam_new:info_button.png?40&nolink}} can be used to display the stiffness values of the CLT panel, the glulam beam and the shear spring, which are the input parameters for determining the effective width.

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

The summary of the results is analogous to the 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.
