Abstract:
Problems associated with design of beam-column joints for shear have been studied extensively in many countries. Work in New Zealand on the performance of joints in reinforced concrete moment resisting frames in seismic zones served to alert designers all over the world to consider these problems. Fundamental studies conducted by Paulay and his colleagues and students contributed immeasurably to our understanding of the behavior of joints. However, the approaches used in design codes have not always been the same as those used in New Zealand. The reasons for these differences have much to do with design philosophies, research objectives, and code development procedures. Shear problems at locations other than joints and in elements where rehabilitation (repair and strengthening) is needed to improve performance of structures under earthquake generated deformations still lack definition sufficient for developing code provisions.
