Experimental Study And Hysteresis Model Analysis Of The Semi-rigid Joint

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 than it is of poor ductility and is brittle destroyed easily. But semi-rigid connections, which is formed by high strength bolts and connecting components, for example angle, end-plate and shape T steel, have an excellent energy dissipating mechanism to resist earthquake loads and prove more capacity for yielding and ductility. In the meanwhile ,the semi-rigid connections can save steel capacity, and become a kind of not only economical, but also reliability connection.Top and seat angle with double web angles semi-rigid connection is of performance ,while few study has for complex destroy and many effect factors. This fund item is based on these reasons to have theory analysis and experimental study .The paper is based on the static experiment to have the quasi-static experiment It studies the damage mechanism under the quasi-static load, get this joint's performance parameter , obtains the hysteresis curve , defines the hysteresis model and the parameter of the model through the data analysis .
