FINITE ELEMENT ANALYSIS ON AN ANGLE CONNECTING JOINT BETWEEN BRB AND CONCRETE BEAM-COLUMN

For the problems of connecting joint between BRB and concrete beam-column,such as stress state, strength and stiffness factors, a new type of angle steel connection node is designed in this paper. Through the finite element simulation of the node under monotonic and cyclic displacement loading, the load-displacement curve, the skeleton curve and the impact on each component of the node are analyzed, the mechanical properties and the force transmission mechanism are also studied. The results show that the structure of the node form, power transmission mechanism is clear. Good work performance are showed under monotonic and cyclic loading.
