Module "Web plates"
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
The input field "General" defines the service class. It is only allowed to use CLT elements in areas of service class 1 and 2.
- Service class 1 (interior service condition) is in general consistent with a common utilisation of living spaces.
- Service class 2 (protected exterior service condition) is generally used for open but roofed structures.
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
In this module, the cross-section is defined by selecting a product.
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
The tab "Vibrations" allows for vibration verification.
For the vibration verification the following specifications are of importance:
- high or normal requirements? This choice will have an influence on the limit values.
- modal damping factor
- consideration of the screed (concrete topping) stiffness
- thickness of the screed (concrete topping)
- modulus of elasticity of the screed (concrete topping)
- support (2-sided or 4-sided)
- room width b perpendicular to the load carrying direction
The effective width bw of the chosen cross section used by the stiffness criteria will be specified.
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 
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.
