摘　　要：某婚庆礼堂采用大跨钢筋混凝土拱柱和拱壳,拱柱的高宽比和拱壳的高厚比分别达到23.6和116.7,需对其进行稳定性分析。本文运用通用有限元软件ANSYS对上述构件进行特征值屈曲分析和考虑几何非线性的稳定性分析。分析结果表明:在结构稳定性分析时须考虑初使缺陷等相关因素的影响,本工程拱柱结构和拱壳结构在设计荷载工况下均能满足稳定承载力要求,并具有安全储备。A stability analysis of a wedding auditorium is carried out, using the large-span arch shell and arches whose height-width ratio can respectively reach 23.6 and 116.7. The finite element software ANSYS is used to make the bucking analysis and geometry nonlinear stability analysis. The results show that： the effect of the beginning defects and related factors should be considered in the structural design; the structure of arches and arch shell can meet the requirements of stability and bearing capacity, and can have some safety margins.
