Experimental Study on the Collapse Process of An 18-Story High-Rise Steel Building Based on the Large-Scale Shaking Table Test
Abstract eng: This paper reports on a large-scale shaking table test of a high-rise steel building conducted at the facility called E-Defense. The building specimen is a 1/3-scale 18-story steel moment frame. The input motions were based on the expected longperiod and long-duration strong earthquake. The specimen was subjected to a series of progressively increasing scaled motions until it completely collapsed. The damage of the steel frame began through the yielding of beams along lower stories and column-bases of the first story. After several excitations by increasing scaled motions, cracks initiated at the welded moment connections and fractures in the beam flanges spread to the lower stories. As the shear strength of each story decreased, the drifts of lower stories increased and the frame finally collapsed. From the test results, the typical collapse progression for a tall steel moment frame was obtained, and the hysteretic behaviors of steel structural members including deterioration due to local buckling and fracture were observed.
