The column of soft storey meant for car parking has to be designed for 2.5 times the actual column design moment as per IS 1893-2002 Part 1. Suppose if the building is covered by 3 sides of wall and one side open, is it mandatory to multiply the column moment by 2.5 times. Experts kindly comment on this as per codal provision.

是:1893年,Cl.4.20:——“软层:它是在制作吗h the lateral stiffness is less than 70 percent of that in the storey above or less than 80 percent of the average lateral stiffness of the three storeys above."

That's the definition. Hope it's clear

亲爱的先生我想cunfirm低于警告staad out put
if any analysis of building showing warning of soft storey than v can accept it by designing column by 2.5 factor...or we must make the structure non soft story by increasing stiffness
