摘要
文章建立了钢筋混凝土巨型框架结构有限元模型,并进行反应谱分析,分析表明:分别改变主框架柱刚度、主框架梁刚度对结构抗震性能的影响是不同的;主框架梁层数越多对侧移的控制作用越明显;主框架梁层数一定的情况下,靠近结构下部布置主框架梁比靠近上部布置控制侧移更明显,层间位移角分布更均匀。
The essay discusses about the reinforced concrete mega-frame structure with finite element analysis modeling was introduced to study on the response spectrum analysis.According to the results obtained:the effects are different on the seismic properties by considering the changes of mega-column's stiffness or mega-beam's stiffness;the major beam controls the horizontal displacements more obviously with more layers of it;the major beam controls the horizontal displacements more obviously and drift angle is distributed more evenly when the mega-beam's layout near the lower part of the structure.
