摘　　要：混凝土拱壳结构可以满足建筑所要求的复杂外形,并能很好利用混凝土的受压性能,在实际工程中有众多的应用。银川火车站站房采用了三个清水混凝土拱壳结构,壳体纵向最大跨度27m,体型较为复杂,受力性能特殊。运用通用有限元程序ANSYS对混凝土壳体进行分析,确定其失稳模态,得到拱壳结构对于外载的反应以及自身屈曲性能,探讨了混凝土壳体结构非线性有限元计算的可行性,所得分析结果可为类似结构设计提供依据。Concrete arch shell structure,which can meet the requirement of complex building shape,and make good use of compression performance of concrete,has many practical engineering applications.Yinchuan Railway Station building has three arch shells using bare concrete,which has 27m maximum vertical span,complex shape and special mechanical properties.The finite element analysis program ANSYS was used to analyze the concrete shell and to confirm the instability mode.From the result,the response to the applied force and their own buckling performance of the arch shell structure has been made out.The feasibility of non-linear finite element analysis of the concrete shell structure is discussed.
