I notice that your verification is done using “joint lumped inertia force system”. What is the difference of running the load generation in “member distributed inertia force system”?
It influences the transportation load type created in STAAD.Pro file. If the “Member Distributed Inertia Force System” is selected, the transport loads are created as member loads in the _TRAN.std file. If the “Joint Lumped Inertia Force System” is selected, the transport loads created are nodal loads.
