Dear Jayakumar sir,
Thank you for your reply. Here I want to mention one errata in my posting. The size of building for lumped mass and member weight method as per sketch is 15m x 15m. But in my text it is mentioned as 12mx12m. Kindly corect the size and and read it. In geometry step also length along X and Z is 15m with 5 bays with each bay 3m. If somebody master in Staad pro use different method, kindly indicate the procedure if they want to mention. If anybody wants other procedure on time history, mode shape, natural frequency on rayleigh and eighen value extraction method, I shall post it in this forum for reference. Thank you for the interest shown by members.
V.M.RAJAN.

Dear Rajan Sir,
Thanks a lot for uploading the examples which are really very usefull to all of us.
Can you explain the use of IMB, IPLM and PLASTIC commands to be used while using IS 13920 design in Staad.Pro? Can you give specific example citing when to use or not to use these commands?

with best regards,
Aditya
