| 摘 要： | 采用大型有限元软件ANSYS对巨型框架结构进行了动力时程分析，讨论了不同主次框架刚度比下巨型框架结构的地震响应，计算结果表明，钢筋混凝土巨型框架在地震作用下的侧移曲线为弯剪型；主次框架刚度比对巨型框架弹性地震反应有较大影响；结构的高阶振型对结构反应有一定影响，当与地震波卓越周期相近时可能发生类共振现象。 |
| 关 键 词： | 巨型框架结构 ANSYS软件 类共振现象 动力时程分析 |

| Abstract: | Using the ANSYS finite element program,it was analyzed the earthquake resistance to the mega-frame structure.The eseismic responses of mega-frame structure under different frame rigidity are discussed in detail.The calculated results show that the displacement curve of reinforced concrete mega-frame structure is a type of flexure-sheer.The proportion of the major and the minor frame stiffness is an important factor which influence the elastic seismic response of mega-frame structure.The structure higher ord... |
