Nonlinear seismic analysis of steel frame with semi-rigid joints

Paulina Krolo, Mehmed Čaušević, Mladen Bulić

Abstract

The nonlinear seismic analysis of steel frame without diagonals is presented in the paper. The real behaviour of semi-rigid joints is taken into account through prior numerical simulation of the selected type of joint. The resulting bending moment and rotation curve is substituted with trilinear approximation and incorporated in seismic analysis according to the nonlinear static N2 method. Absolute and relative frame displacements are determined, and the corresponding results are compared with results for the steel frame with absolutely rigid joints.

Keywords
seismic analysis, steel frame, semi-rigid joints, numerical analysis, nonlinear static N2 method
