Frame systems should be designed to be of beam collapse mechanism to avoid the occurrence of "soft story". But it is difficult to design a frame to be of weak beam-strong column type, due to the insufficient understanding at present stage on the cooperative effects of slab reinforcement as well as the simultaneous developement of plastic-hinges in all the beams that frame into the column when subjected to a skew earthquake attack. This paper presents the shaking table tests conducted on the multi-story plane frame structures, with an aim to verify the validity of the limit state design method(LDM) which is considered to replace the currently used elastic analysis method(EAM). The frame designed according to LEM Is in the way that the strength of beams Is arranged uniformly along the height with total value of strength being the same in the frame designed by EAM.
