Evaluation of Composite Action in the Steel Building Subjected to Seismic Loading (E-Defense Experimental Projects for Steel Building – Part 92)

摘要

In September 2007, a full scale four-story steel building specimen was experimented to collapse on the E-Defense which is the world's largest three-dimensional shaketable located in Miki City, Hyogo Prefecture, Japan. The ground acceleration histories recorded at the JR Takatori station (namely Takatori input motion) during the 1995 Hyogo-ken Nanbu earthquake were used as the input for the shake-table experiments under various scales. Experimental result shows that collapse occurred under the 100% Takatori motion, due to local buckling leading to deterioration of columns in the first story level. To open up the discussion on the building specimen performance in the test, this study evaluates the composite effect of concrete slab on steel girders during seismic loading.
