| 中文摘要 | 为了研究钢管混凝土柱与钢筋混凝土基础之间的柱脚连接性能,采用ANSYS软件进行了钢管混凝土柱脚在单向加载和低周期反复加载下承载性能的有限元分析,明确了柱脚中性轴的变化规律,给出了单向加载下柱脚的破坏特征,分析了低周反复荷载下该柱脚节点的滞回性能。研究表明:该柱脚节点的工作性能可靠,总体抗震性能良好;随着轴压比的增大其抗震性能表现出先增强后减小的趋势。; In order to study the behaviors of connection between concrete filled steel tubular column and reinforced concrete foundation,the bearing capacity of the column foot is analyzed by ANSYS FE models under uniaxial loading and repeated low cycle loading respectively.The change pattern of neutral axis is obtained.The static loading damage characteristics and hysteretic behavior of the tubular foot are analyzed.The analysis shows that the tubular foot is featured with excellent working performance and high seismic behavior.The seismic behavior of the tubular foot firstly increases and then decreases with the axial compression ratio increasing.; 河北省自然科学基金资助项目(E2009000893) |
