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.
