HI ,
I am new with staad, so ur small help will also favour to me, I am using staad for analyzing skid, but there is two layers of stiffners connected to main beam(W24x55), for this I made parallel stiffner beams by offsetting them from same node, but while analyzing so many errors are there and shows master slave problem and elasticity is not provided. but while chosing a section it will automatically takes the E value, then why it asks like that, ahether I need to change my model
