| 中文摘要 | 为研究钢-混凝土组合节点刚度对组合框架抗震性能的影响,首先讨论了组合节点的刚度及其影响因素,然后通过某多层钢结构工程实例,利用Ansys有限元软件建立了纯钢框架与组合框架,分别假定刚接及考虑节点刚度等共4种框架模型,进行了多遇地震反应谱分析及弹性时程分析,并进行了计算对比.计算结果表明,考虑钢框架的组合作用后,结构整体自振周期变短,基本自振周期降低了13.4%,说明结构整体刚度变大.但考虑节点刚度后,地震周期又有所加大,纯钢框架及组合框架基本自振周期均增大了17%,相应地震位移变大,2种模型的反应谱法分析顶层位移分别增大了8%,11%,说明组合节点刚度对结构的抗震性能是不可忽略的因素.; To study the main influence of composite joints rigidity on composite frame seismic properties,this paper at first discusses composite joint rigidity and influence factors,and then through a multi-storied steel project,creates frame composite frame and different joint style four model based with finite element software ANSYS,and contrasts the results of response spectrum analysis to elastic time-history analysis.The results which take the composite effect into account show that the natural vibration period is shorter by 13.4%,the stiffness of the structure is larger than not.But considering the rigidity of joints,the natural vibration period is larger by 17%,the drifts of earthquake are larger,and the top drifts is larger 8% and 11%.the rigidity of composite joints can not be ignored in earthquake.; 国家自然科学研究基金资助项目(50578083) |
