Second-Order Effect of Staggered Truss and Simplified Formula
This paper summarizes the regulations about steel frame second-order effect of some design code in the world, and find out a critical factor of controlling second-order effect. The second-order effects of staggered truss were studied systematically by using ETABS program, and put forward design proposals the second-order effects of internal force and displacement, the simplified formula on second-order effect magnification factor of displacement was given.
