摘　　要：为研究L形钢管混凝土柱在抗震性能方面的特点,并推广其在建筑结构中的应用。通过利用ABAQUS软件进行计算分析,以轴压比和钢管厚度作为参数,研究L形钢管混凝土柱的滞回曲线和骨架曲线。同时,结合实际建筑结构设计,利用ETABS软件进行整体框架结构的抗震计算。研究结果表明,L形钢管混凝土柱具有施工简便、装配性高等优点,在提高建筑抗震性能方面具有应用潜力,适合在村镇建筑中广泛推广使用。In order to study the seismic performance of L-shaped concrete-filled steel tube columns and promote their applications in buildings,the hysteretic curve and skeleton curve were studied by calculation and analysis with ABAQUS software,taking the axial compression ratio and steel tube thickness as parameters.Moreover,the seismic calculation of the whole frame structure was carried out with ETABS software in conjunction the actual building structure design.Results show that L-shaped concrete-filled steel tube columns have the advantages of simple construction and high assembly performance.They have application potential in improving the seismic performance of buildings,so they can be widely applied in rural buildings.
