HYSTERETIC BEHAVIOR OF THE CONNECTION BETWEEN RC FRAME BEAM WITH FLOOR AND ENERGY DISSIPATION LINK
According to the cyclic tests of a total of five full-scale connections between a RC Frame beam with floor and an energy dissipation link, the force transferring mechanism and failure modes of test specimens were systemically studied, and the hysteretic behavior, lateral strength, deformability, ductility, stiffness, and energy dissipation were analyzed. The hysteretic curves of test specimens were simulated through ABAQUS. The results show that the connection via U-shape steel is simple and reliable. The action of floor can increase the lateral strength and post deformability. The separation between the end plate of an energy dissipation link and the top interface of a RC beam leads to the pinching phenomenon of hysteretic curves and poor energy dissipation.
