Outline of Final Research Achievements

The purpose of this research is to investigate the three-dimensional collapse behavior of steel building structure under severe earthquake and make the safe margin of earthquake resistant design clear. For the evaluation, it is necessary to do the response analysis which reflected realistic behavior of constructional members. In order to evaluate the hysteretic behaviors of columns and beams, some series of three-dimensional cyclic loading test on RHS columns and a series of cyclic loading test on composite beams were conducted. Also, research team worked on development of an analytical program for three-dimensional collapse behavior of steel frames.
