Description
This paper presents the dynamic collapse analysis of a full-scale four-story steel building which was experimented to collapse at the E-Defense shaking-table in Japan, in 2007, using the ground acceleration histories recorded at the JR Takatori station during the 1995 Hyogo-ken Nanbu earthquake. Deterioration of columns on the first story level due to local buckling is thought to be one of major reasons for the building collapse. Fiber method approach is adopted in the analysis to simulate local buckling at the column ends. Hypothetical analyses estimate the collapse capacity of the building specimen at approximately 0.9 times Takatori ground motion level. The collapse capacity of the building specimen under various propagating directions of the non-scaled Takatori ground motion is also investigated, showing that the building likely collapses under any propagating direction of the ground motion.
