Abstract

Abstract

Based on the ideas of damage control and buckling-restrain, the paper proposed a kind of earthquake-resilient ductility-reinforced prefabricated opening-web steel channel beam-column joint. The seismic behavior of 4 examples was studied by finite element method. The hysteretic curves, failure modes, stress distribution and relative displacement curves of the plates were obtained. The influence of the parameters such as the thickness of the flange cover plates, the width of the dog bone weakening section and the number of bolts on the seismic behavior of the joint was emphatically studied. The results showed that the bearing capacity and seismic behavior of the joint were good. The plastic hinge could be transferred to the flange cover plates effectively, at the same time, the main components such as beam and column were basically elastic at the elastic stage. Therefore, the function of joint could be restored by replacing the connecting device after earthquake. The U-shaped web connecting plates could effectively restrain the buckling deformation of the inner flange cover plates, and improve the ductility of the joint. In addition, parameters which had a great influence on the seismic performance of joints such as thickness of inner flange cover plates, width of dog bone weakening section and number of bolts should be designed reasonably.
