[ 摘要] 某奥运场馆平面近似椭圆,长轴 144 米,短轴 130 米,总高度米。规模较大,结
构复杂,用一般的软件很难得到满意的结果,为此使用了大型结构分析软件——
对建筑结构进行了合理的建模,并对其进行了静力和模态分析,在静力分析
中进行了各种荷载组合,得出了梁、柱、墙、板等构件的变形、轴力、弯矩等结果,提
出了该结构的薄弱构件,对结构设计有一定的参考价值;并得出了该结构的前 40 阶频率
和振型,并对振型特点进行了分析。

[ Abstract ] The plane of a Olympics building looks like oval. The length of major axis is 144
length of minor axis is 130 meter. And the length of height is meter.
The scale is large and the construction plicated. It is not satisfied with using the
general software,so a reasnoble modeling is created by large-scale structure analysis
