Abstract


The economic recovery has brought a lot of continued construction works . Engineering continued construction process , often encounter the old and new concrete connections and work together . When such problems in the framework structure node , the already complex node force performance more bewildering . This paper based on the idea of finite element , calculated with the framework of the old and new concrete handover surface seismic performance analysis using ANSYS software , and compare two different methods of reinforcement - bonded steel reinforcement method and carbon fiber reinforcement method , the impact of the seismic performance . Calculated results from the ultimate strength, ductility , joint stiffness , and energy dissipation capacity compared two reinforcement methods for seismic performance improved in different degrees ; bonded steel reinforcement method showing stronger in some respects , superiority. The article also summarizes the composite static analysis using ANSYS experience , a brief analysis of the complex node grid cells divide and calculate the parameters set , and hope to be able to provide some reference to other researchers .
