【Abstract】 In order to investigate the flexural resistance of semi-rigid connections,a formula was deduced based on the simplified slope-displacement equation to calculate the initial stiffness of the semi-rigid connection with top-and-seat angles.The ultimate moment of the connection was then obtained according to the plastic characteristics of the angle.Moreover,the flexural behaviors of two types of semi-rigid connections of column minor axis with top-and-seat angles were experimentally discussed.The moment-rotation characteristics of the above-mentioned connections were finally simulated by using the three-parameter power model.The results show that the simulated results accord well with the experimental ones,and that the new connection form designed in this research possesses good moment capacity.更多还原
