摘要
为了研究不同因素对部分包裹混凝土柱(PEC柱)-型钢梁框架组合结构抗震性能的影响,利用大型通用有限元分析软件ABAQUS,对其进行了非线性静力数值模拟研究,以轴压比、系杆间距为主要参数,模拟分析了在上述参数变化情况下该结构的滞回曲线、骨架曲线、延性以及耗能能力。结果表明:PEC柱-型钢梁框架组合结构抗震性能良好,该模拟研究为以后试验研究提供了合理的理论依据和参考,具有一定的学术和工程应用价值。
In order to study the influence of different factors on the seismic performance of partially encased concrete composite column（ PEC）-steel beam frame structures,nonlinear static numerical simulation study was carried out by using ABAQUS. The hysteretic and skeleton curve ductility and energy dissipation of the structure were analyzed under different axial compression ratio,tie bar spacing. The results showed that the seismic performance of PEC column-steel beam composite structure is good. The simulation study provides a reasonable theoretical basis and reference for the future experimental research and has a certain academic significance and engineering application value.
