A Study Of Vertically-Loaded Transfer Joint Of T-shaped RC Wall

According to test results of three specimens of transfer joint of T-shaped RC wall under vertical static loads and results of corresponding nonlinear finite element analysis (ANSYS), fundamental behaviors of the joint are achieved, which include path of vertical load transfer, stress distributions, occurrence and development of cracks and final failure mode of the joint. In the test, the influence of armpit height of the transfer beam upon mechanical behavior of the joint are specially studied and a conclusion is reached, that is, the armpit height has effects not only on the capacity of the beam itself but also on the stress states, failure mode and ultimate capacity of the T-shaped wall. At the same time, the influences of detailing of reinforcement in the joint upon mechanical behaviors of the specimens are also studied. The result of nonlinear finite element analysis agrees with quite well with those of experiments. On the basis of experimental and analytical achievements, calculating methods for the transfer beam and the T-shaped wall as well as detailing of the joint are. suggested.
