摘要
装配式钢筋混凝土结构的整体稳定性和抗震性能受预制件间连接方式和连接性能的好坏影响较大,而整个结构的强度和整体性又直接取决于梁柱节点间的连接。通过ABAQUS软件建立装配式钢筋混凝土梁柱节点有限元模型,对影响结构整体性能的关键参数进行数值分析,总结并分析了装配式梁柱结构在不同梁端配筋率及轴压比的情况下对装配式混凝土梁柱抗震性能的影响,为保证装配式钢筋混凝土梁柱结构安全施工和进一步提高装配式钢筋混凝土梁柱结构的安全性提供了理论借鉴。
The overall stability and seismic performance of prefabricated reinforced concrete structure are greatly affected by the connection mode and connection performance between prefabricated parts,and the strength and integrity of the whole structure are directly dependent on the connection between beam and column nodes.This paper establishes the finite element model of prefabricated reinforced concrete beam and column nodes by ABAQUS software,summarizes and analyzes the effect on the seismic performance of different ratio and axial pressure ratio,to ensure the safety construction and further improve the safety of prefabricated RC beam and column structure.
