Pseudo-Dynamic Test of Steel Frames with Semi-Rigid Connections
半刚性连接钢框架的拟动力实验研究

In steel frame design, the joints between columns and beams are usually assumed as either rigid or perfectly hinge connection. Actually, the joints are semi-rigid connected. in the Literature shows that current experimental studies of frame structure and components are mainly based on static loading. An experimental study of pseudo-dynamic response for typical steel frames was carried out, the influence of steel frame initial joint rigidness on the floor stiffness, base shear, floor displacement and floor acceleration was obtained. Experimental results show that on the premise that lateral displacement meets the specification requirements, the weakening of stiffness of the connection will lower the structure effect. Some conclusions about the effects of semi-rigid connection on the structure performance are conducted, which may give an experimental foundation for the future revision of highrise steel structures design codes.
