Abstract:
Performance of reinforced concrete frames is highly dependent on detailing of the joint connections between its members, such as beams and columns. To have a good structural behavior, joints must show ductile behavior and designed based on the philosophy of strong column-weak beam. In the case of sever lacking ductility, strength or even rigidity of the connections, or having a weak column-strong beam, in the existing structures, there is a need for seismic upgrading of the connection. There are several ways for seismic upgrading of this type of connections.In this research, using steel plates for seismic upgrading of Concrete Beam-Column connections subjected to axial and cyclic loads has been investigated using finite element method. Some empirical results are used to verify the finite element approach. Analyses are then conducted on main models upgraded with steel jackets in beam, column or both using parameters like beam jacket thickness, column jacket thickness and axial load ratio. The results from various methods are compared and the suitable model is proposed
