Abstract

Motivated by an unprecedented steel-structural failure in high-rise buildings due to the 1995 Kobe Earthquake, the authors study the essential causes by simulation analysis, and propose measures for future improvement in earthquake-resistant structural design. Brief description of the constituent mega-structure and the failure patters is followed by exposing the characteristic features of the earthquake excitation and the adopted analytic tools. The results include the conclusion that the large amplitude and ground motion characteristics are mainly responsible for the seemingly brittle fracture in heavy steel columns and breakage rupture in a brace-column joint; the induced responses exceeded the structural capability, causing excessive stresses in the steel members.
