How To Use the SET FLOOR LOAD TOLERANCE Command to Ensure Proper Floor Load Generation

 

Occasionally the members being loaded by a Floor Load will have end nodes slightly out-of-plane with respect to one another.  If this "out-of-plane-ness" is large enough, it can prevent the load generation from working properly, in which case the following warning message will appear when you click on the load:

To get around this, you can add the SET FLOOR LOAD TOLERANCE command in the input file using the STAAD Editor.  This command should be given a value slightly greater than the distance by which the nodes are out-of-plane.  For example, suppose you have a model with nodes that deviate from being coplanar by 0.09 feet.  You could add the command SET FLOOR LOAD TOLERANCE 0.1 as shown below:

Please note, it is important to make the tolerance as small as possible because if it becomes too large problems can arise in the loading and the diagram will become distorted as shown here:
