INELASTIC RESPONSE BEHAVIOR OF BEAM FRACTURED STEEL BUILDING STRUCTURE SUFFERED FROM THE 1995 HYOGOKEN-NANBU EARTHQUAKE

Abstract

This paper presents the results of earthquake response analysis of the beam fractured steel building structure that suffered from the 1995 Hyogoken-Nanbu earthquake. In order to estimate the earthquake input energy and inelastic behavior of fractured beam end, the comparison of analytical predicted and observed damage was carried out. From the results of the analysis, it was presumed that the hysteresis energy input (VD) in this building was more than 300 cm/sec.. And effect of energy absorption of joint panels on reduction of beam damage was also discussed in this paper.
