1.As per IS 1893 (Indian Code) earlier version, for design of members in open or soft storey, we have to multiply the moments and shears of columns and beams in soft storey by a factor 2.5.
How can I achieve this in Staad.Pro. What commands are required.
2. I used Mmag command to multiply the moment but it is not working. Still shear is not addressed.
3. How to get the storey stiffness print out.
4. How to get the storey shear printed out.
Kindly help me.

My Response to Q-1. Please note that this requirement has been removed from the latest version of IS:1893 Part 1. The older code has been subsided by IS 1893 Part 1: 2016. There has been some special requirements to deal with open storey. We need to increase stiffness of that storey only by introducing RC Structural walls or by using braced frames. We need to check stiffness of that storey and it should not be less than 90% of that of the storey above.
My Response to Q-2. This is not required as per IS 1893 Part 1: 2016
My Response to Q-3. Please refer https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/104916/story-stiffness
My Response to Q-4. Use PERFORM ANALYSIS PRINT LOAD DATA command.
