摘要

摘要: 为研究型钢连接装配式混凝土(PC)梁柱节点的抗震性能,采用通用有限元分析软件对型钢连接PC梁柱节点的滞回曲线和骨架曲线等抗震性能指标进行了分析。通过对比分析以及改变节点参数,探讨了柱顶轴压比、钢材强度等参数对节点抗震性能的影响。采用叠加法和曲线拟合法,提出了型钢连接PC梁柱节点总耗能简化计算式,并与多篇文献研究结果进行了对比,验证了算式的可靠性。研究结果表明:型钢连接PC梁柱节点抗震性能好,节点的混凝土强度、钢材强度、型钢厚度和梁柱截面高度均对节点抗震性能影响明显,节点总耗能的简化计算式具有较高的计算精度,可用于型钢连接PC梁柱节点及现浇钢筋混凝土节点的总耗能计算分析。

Abstract: In order to study the seismic performance of PC beam-column joints connected with section steel, the general finite element analysis software was used to analyze the seismic performance indexes such as hysteretic curves and skeleton curves of PC beam-column joints connected with section steel. Through comparative analysis and changes of joint parameters, the influence of axial compression ratio of column top and steel strength on seismic performance of joints was discussed. By using the superposition method and curve fitting method, a simplified formula for calculating the total energy consumption of PC beam-column joints connected with section steel was proposed, and the reliability of the formula was verified by calculating with the results of several literature. The research results showed that the seismic performance of PC beam-column joints connected with section steel was good, the concrete strength, steel strength, section steel thickness and beam column section height of the joints had obvious influence on the seismic performance of the joints, and the simplified calculation formula of the total energy consumption of the joints had high calculation accuracy, which can be used for the calculation and analysis of the total energy consumption of PC beam-column joints connected with section steel and cast-in-place reinforced concrete joints.
