Abstract
Shaking table test of full-scale 4-story building was carried out at E-defense. The objectives of this experiment are to evaluate structural and functional performances of the steel building under design-level ground motions, and to determine the safety margin against collapse under exceedingly large ground motions. This paper presents detailed results concerning the nonlinear responses of the specimen by 0.4 and 0.6 times Takatori records of 1995 Hyogoken-Nanbu earthquake. The cause of difference between the mechanism assumed in design and the mechanism actually generated in experiment is investigated from elasto-plastic behaviors of structural members under three dimensional external forces.
