Roof Panel Properties

Use the Roof Panel properties to view or modify the properties of a wall panel.

The Roof Panel command is used to create a roof panel. Once created, the panel properties can then be viewed or modified in the Properties Window:


Property	Description
General
Plane	Describes the level at which the panel was placed.
Rotation angle	This value determines the following where appropriate: Span direction for 1-way load decomposition Orientation of semi-rigid 2D elements in the Solver Model See: Rotation angle for slab items and panels and Modify slab/panel span direction
Include in diaphragm	The options are: Checked The roof panel is meshed to form a diaphragm of semi-rigid 2D elements. Unchecked (Default) No diaphragm is defined on the roof panel.
Thickness	Roof panel thickness Note: Only displayed if "Include in diaphragm" is checked
Youngs Modulus	Youngs Modulus Note: Only displayed if "Include in diaphragm" is checked
Shear Modulus	Shear Modulus Note: Only displayed if "Include in diaphragm" is checked
Temperature coefficient	Temperature coefficient. Note: Only displayed if "Include in diaphragm" is checked
Divide Stiffness by	Used to adjust the roof panel stiffness. Note: Only displayed if "Include in diaphragm" is checked
RoofType	The options are: Default (Default) Flat Monopitch Duopitch Hip Gable Hip Main Mansard Note: The default option assigns the roof panel as flat (if the slope < 5 deg) or Monopitch (if the slope is > 5 deg). You can more accurately specify the roof panel by choosing the appropriate option from the list. Note: If the RoofType is changed after the wind model has already been established, you will need run Update Zones to reinstate the zoning.
