本文报道了在E-Defense设施进行的高层钢结构建筑的大型振动台试验。建筑试件为1/3比例的18层钢框架。输入运动是基于预期的长周期和长持续时间的强震。标本受到一系列逐渐增加的比例运动，直到它完全崩溃。钢框架的破坏是从一层较低楼层和柱脚的横梁屈服开始的。经过几次按比例递增的运动激励后，焊接弯矩处开始产生裂缝，梁翼缘的断裂扩展到较低的楼层。随着每一层的抗剪强度降低，较低层的位移增加，最终框架倒塌。根据试验结果，得到了高层钢框架的典型倒塌过程，并观察了钢结构构件的滞回性能，包括局部屈曲和断裂引起的劣化。
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.
