Abstract:
Summarizes a series of research efforts at the University of Tokyo leading to the development of earthquake-resistant design criteria for reinforced concrete interior beam-column joints. The design criteria emphasize the protection of the joint to an acceptable deformation level of a frame structure during an intense earthquake. For the design against shear, shear-resisting mechanisms by truss and concrete compression strut, the role of joint lateral reinforcement, and the effect of transverse beams and slabs were studied experimentally. The requirement for beam bar bond was discussed on the basis of nonlinear earthquake response analysis.
