柱、はり接合部の補強効果と復元力特性(開学10周年記念号)

In general, we use the hyposes that the joints of framework are rigid when we analyze the frame structure. Namely the area of the joint is not taken into account. This idealization, however, is doubtful for actual structure especially for steel structures. The beam-to-column connection, ie, the panel zone will be fairly deformed during the strong motion earthquake. The authors examine, in this paper, the stiffness of panel zone and carried out the experimental work on the restoring characteristics and the stiffening effect of panel zone of usual wide flange. The experimental results are described in detail herein
