Abstract
The experimental study on response of reinforced concrete slab-beam-column connections to unidirectional and bidirectional seismic loads was conducted at the University of Texas at Austin in the United States as part of the US-New Zealand-Japan cooperative research program on earth-quake-resistant design of beam-column joints. This paper outlines the US tests and compares the test results with those in New Zealand and Japan, focusing on the ultimate load carried by the beam-column joints. The shear strength of the joints under unidirectional and bidirectional loads is discussed herein based on the test data in the US-NZ-Japan research program and those reported elsewhere.
