| The joint between beam and column is the key of the designation of high-rise building.In order to resist the structure's lateral load and reduce the lateral displacement efficiently in the tier or tall building structure , it is generally designed the joint as rigid joint earlier. But several earthquake has proved that it is of poor ductility and is brittle destroyed easily.So people begin to put their eyes on the semi-rigid joint which connect the beam and column by high strength bolts and connecting components, for example angle, end-plate and shape T steel.Therefore,the paper is dedicated to study a new type joint-top and seat angle with double web angles semi-rigid connection. The research of this connection under cyclic loading is simulated using powerful finite element analysis software.The damage mechanism under the moment loading is studied and the hysteresis curve is obtained, the hysteresis model and the parameter of the model is defined to provide academic and numerical foundation. The research on the hysteresis behavior and power consumption behavior of this joint under the cyclic loading is completed. Numerical Simulation on top and seat angle with double web angles semi-rigid connection with different parameter is done and the influence of different parameter to the behavior of joint is analysed. |
