SIR I WANT TO KONW WHY MASS IS PROVIDED IS PROVIDED IN GX AND GZ DIRECTION IN MASS REFERENCE LOAD CASE.
Hi,
It is not necessarily the mass load has to be directed in X or Z only - it can be applied in all three directions. Please refer to STAAD.Pro Help manual chapter TR.31.8.3 Mass Model Using Reference Load.
when im putting seismic load at y direction its showing error
