Auto Seismic Analysis in STAAD PRO


I have been doing Seismic Anaysis of buildings using Auto Lateral Load option, i have a question, while assigning the Seismic Defination (IS 1893-1984), I have applied seismic self weight, member weight & floor weight. Is it necessary to add Joint weight also??? What is the correct procedure for applying auto lateral load in Staad Pro for RCC Buildings?

I am using Staad Pro 2006.

Thanks in advance for my query..
