Abstract:The pseudostatic force test of semirigid connections with bolt in steel frame under cyclic loading was carried out to obtain the hysteretic behavior. The rotational stiffness, carrying ability, ductility coefficient and energy consumption mechanism were analyzed,and the differences of three types of connection were discussed. According to the results of test, it is shown that the thickness of T type steel flange is the main factor affectin
g the connection behavior and the effect of web angle should be taken into account when calculating the rotational stiffness and the carrying ability of the topbottom angel with double web angel connections.
Keywords:steel frame; bolt connection; hysteretic behavior
