| Abstract: | Reversed cyclic-load tests on full-scale RC exterior beam-column joints, which are fabricated to simulate those in as-built reinforced concrete framed buildings designed to BS 8110, are carried out. Emphasis of the study is placed on the effects of the types of beam bar anchorage on the seismic behaviour and shear strength of reinforced concrete exterior joints subjected to simulated earthquake load. The behaviour is investigated with different types of anchorage in beam reinforcement. It has been shown from the experiment that all the specimens have low ductility capacity and poor energy dissipation ability. The test results are compared with two preseismic design codes (BS 8110 and EC 2). It is shown that the types of reinforcement anchorage in beams have significant effects on the shear capacity and hysteretic behaviour of exterior beam-column joints. Present codes of practice do not accurately predict the shear strength of the non-seismically detailed joints. It is indicated that ignoring the design of beam-column joints may lead to potential damage of reinforced concrete framed buildings in an unexpected low to moderate earthquake. | |
