Diaphragm loads and diaphragm load tables
Diaphragm loads are Building Direction 1, Building Direction 2, and Mz torsion loads applied at any point within a rigid or semi-rigid diaphragm.
Typically these might be used for the application of externally determined level loads (for example from Wind Tunnel testing of large/ unusual structures).
The Diaphragm load command is available when a 2D plan view is active - it can be used to apply a load to any diaphragm within the current view.
If you have multiple loads to apply at different levels, the Diaphragm Table of loads provides a quicker means of doing this - either by typing the loads and their positions directly into the table, or by pasting the data into the table from a spreadsheet.
Add a diaphragm load in a 2D view
Add a diaphragm load in a 3D view
Add a diaphragm load in a 3D view by selecting the diaphragm level
In this method, the load can be applied to a diaphragm at any level by selecting an existing point at any level:
Add multiple loads using the diaphragm load table
Paste multiple loads into the diaphragm load table
- Force in direction 1
- Force in direction 2
- Torsion moment
- Position X
- Position Y
- Position Z
