I have been designing an RHS with a base plate and gusset stiffeners. I've used master-slave command for the location of my loads and used Plate Mat Support as supports. The error was always "ERROR IN SUPPORT INPUT OR THERE IS NO SUPPORT INPUT. ANALYSIS WILL NOT BE PERFORMED. DATA-CHECK MODE ENTERED." even though the support command is clearly present in STAAD Command Editor, and acccordingly arranged with SLAVE command. What must be the error and solution for this?Alternatively, I used plain pin supports located at every node of the plate of my model base plate. No error was found with this said model. How reliable is this compared to using Plate Mat Support? Thank you in advance!Note: I'll post my model files after the shift. Local network has been locked for now.
From the description it seems there is some issue in the plate mat support specification in the model. We will wait for the model to check and provide a solution.
