In recent years, the development of computer hardware and software has brought many advantages in solving non-linear problems and has formed many different methods to predict the exact form of steel frame destruction, reflecting closer to the actual work of the steel frame. The nonlinear of geometry, nonlinear of material behavior and the analysis of the structural system are combined in one step. This article firstly mentions "steel frame analysis taking into account the structural integrity of the American Standard System AISC-PRFD (2010)".
