Abstract:
SP123 This volume is a collection of technical papers on the aspects of design of beam-column joints for seismic resistance. Nineteen papers are divided into the following groups. - Tests conducted on specimens designed using current codes but with the same general geometry and a specified loading history. (4 papers) - Design recommendations -- Japan. (1 paper) - Influence of joint geometry on strength and deformation characteristics. (8 papers) - Influence of bond on joint performance. (4 papers) - Joint in precast systems and with high-strength materials. (2 papers)

Three reinforced concrete beam-column connections, each with a slab were tested under the U.S.-Japan-New Zealand-China cooperative research program on design of beam-column connections. Two of the specimens were subjected to both unidirectional and bidirectional cyclic loads. Results of the tests are described with the aid of story shear drift angle relations, story shear orbits, measured joint shear deformations, and plots of drift angle components. Various methods for calculating joint shear strength are evaluated in light of the test results. Test data are also used to determine slab effective widths for use in calculation of uncracked beam stiffness and beam flexural capacity.

The results of three full-scale reinforced concrete beam-column joint specimens subjected to one- and two-directional reversed loading are presented in this paper. The influences on aseismic behavior of beam-column joints with different loading systems and monolithic slabs have been analyzed. Also, the relevant provisions for joints in the Chinese design code for reinforced concrete structures have been checked by test results, and some recommendations for beam-column joint design are given.

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.

The Architectural Institute of Japan (AIJ) published its 1988 draft design guidelines for earthquake-resistant reinforced concrete buildings based on ultimate strength concept as a first attempt to develop an ultimate strength design procedure in Japan. This paper introduces the general concept of the design procedure, and explains in detail the design requirements and background information for reinforced concrete beam-column joints of the AIJ guidelines. Based on experimental evidence, the amount of lateral reinforcement in the joint required is significantly reduced from ACI requirements.
