Simple wind load example (panels)

The example consists of a two level building clad in wall and roof panels.
A simple wind load is applied at one end of the building. The load is uniform, applied to wall panels, and extends over the full building height, but not the full building width (as shown below).
The resulting simple wind load is as shown below:
During analysis the simple wind load is applied to all panels within the load width and height that are facing the wind. For this example only the two panels highlighted below meet these criteria.
After analysis, the actual loads applied to the panels are highlighted below. These are in the form of polygonal area loads. (Because Decomposed Loads are switched on in Scene Content these are also being displayed on the members supporting the two panels).
Note: The following points should be noted in the above view:
  • When applying simple wind loads to panels, the model is treated as an open structure. Therefore the simple wind load is ‘seen’ by both of the windward facing panels.
  • The simple wind load has exactly the same area as the left hand panel and is applied over the panel's full width and height.
  • Although the simple wind load is less wide than the right hand panel it still gets applied over the panel's full width. This is because only part of a panel width is required to overlap with the simple wind load width for it to be applied over the full panel width.
  • Vertically, the simple wind load width does not overlap with the right hand panel until Level 1, thus it is only applied to the panel above that level.
