Simulation and Analysis of Energy Dissipation Capacity of Asymmetric Hybrid Connection Nodes
The mechanical reliability of assembly connection nodes is the key to ensuring the overall performance of prefabricated structures.Taking concrete nodes as the research object,the DRAIN-2DX finite element analysis software is used to analyze the hysteresis curves of three different hybrid connection nodes in prefabricated frames.The energy dissipation capacity of hybrid connection nodes under different assembly methods is analyzed.Furthermore,the reasonable values of the reinforcement ratio of ordinary steel bars and the initial unconnected length,as well as the initial effective prestress of prestressed bars in asymmetric hybrid connections are further studied,providing strong reference for the design of asymmetric hybrid connection frames.
