Theory Analysis And Experimental Study Of The Semi-rigid Steel Frame's Joint System

In order to resist the structure's lateral load and reduce the lateral displacement efficiently in the design of tall building structure , the engineers generally design the joint as so-called "rigid joint". Though this idealistic hypothesis can simplify the design and analysis process largely , it engenders the large difference of theory and practice, the structure's insecurity or conservation and uneconomicalness,specially in the case of earthquake ,a large quantity of earthquake examples have proved it.Therefore ,the paper is dedicated to study a new type joint-top and seat angle with double web angles semi-rigid connection ,which has good resistance to vibration on the base of large quantity of alien data.lt 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.
