Hi Santhosh,
Instead of lumped mass STAAD 2005 their is floor weight and that'll be much useful than lumped mass. You can use that option.

Hi Santosh,

One methode is to model pinned supports at node points of main frame
members, and run staad for reaction for dl+LL+Equipment load(If any).

Use these reaction as mass load for generation of seismic analysis.
