How does one get a report indicating whether the applied loads are in equilibrium with the support reactions?
There is an option which can be provided along with the PERFORM ANALYSIS command for getting this information. It is called PRINT STATICS CHECK. It is explained in the STAAD.Pro Help section Technical Reference of STAAD Commands > TR.37 Analysis Specification > TR.37.1 Linear Elastic Analysis.. The sample below shows how this is done.

If you prefer to use the graphical method for specifying this option, this is how it can be done.
In the Analytical Modeling workflow, go to Analysis and Design > Analysis Commands in the ribbon menu. A Perform Analysis dialog box will be displayed. Set the radio button on Print Statics Check. Click on Add.
Save the file and run the analysis. Then view the output file. (This can be done from Utilities > Analysis Output menu). If you scroll down to the region where the PERFORM ANALYSIS command is specified, the equilibrium report will be available after that command.
