You can always directly define the seismic weight. Once you go to Seismic Definitions and choose a building code, you will get options to define various types of weights including floor weight.

Seismic load generation as per any of the codes follow the same process. You can find videos on the Bentley learnserver at

Thank you so much, sir. Can you please help regarding the first part of the question where I can directly give seismic loads instead of converting them by copy-pasting from Dead and Live Loads. Is there any guide video by Bentley to assign loads according to IS 13920? Thanks in advacne.

Seismic loads( equivalent static load) if defined, would have to be physically located as the first load cases in the input editor ahead of any other loads like DL or LL. There is no engineering justification behind it. It is more of a software requirement so that the data can be read properly. So you can always define DL and LL first and then use these to define the seismic weights. There is no harm if your DL is Load 1 and LL is Load 2 and your seismic load is load 100. However you need to later use the editor to move the Load 100 ahead of your load cases 1 and 2.
