Aim of this paper is to propose a simple method on the non-linear analysis for semirigid connection frames under static and dynamic loading. A hybrid element which has a inelastic element and a one-node zero length connection element with three rotational degrees of freedom is used to model the nonlinear behavior of steel beam-column with semirigid joint. The hysteresis rule for the semirigid joint is also assumed here. Considering the slip effect, which is commonly found on some type of semirigid connection, a simple Slip-trilinear Model is proposed. With this analytical method, a portal frame with semirigid connection (with brace or no brace) under monotonic loading is analyzed to show the static behavior of semirigid frames. Furthermore, a dynamic analysis on a two-story frames both with semirigid connection (split-tee) and fully-rigid connection is undertaken and compared with the responding sub-structuring pseudo-dynamic test result. It is shown that the dynamic response from the test is very accurately predicted by the analysis.
