Abstract

Abstract

Eccentrically braced steel frames is a kind of steel structure of tall building with well resistan-t seismic and energy-dissipation. A new analytical model in which degenerate shell element applies to link beams with large deformation and plastic deformation and beam element applies to other parts of structure is presented. In the process of finite element analysis, geometrical nonlinearity is taken into account for the beam element, while geometrical and material nonlinearities are taken into consideration for the shell element, together with mixed hardening rule. Computer program is complied. Good agreement for analyzing eccentrically braced steel frames energy- dissipation behavior is found between the theoretical predications and experiment result.
