摘　　要：对杆件稳定计算中的两个重要因素——杆件计算长度和容许长细比进行分析研究,提出杆件计算长度的近似计算方法,并给出网壳结构杆件在壳体曲面内及曲面法线方向的计算长度系数的取值和容许长细比数值,供设计人员采用.The determining methods of steel latticed shells member's calculated length in internal and normal direction of curved surface are developed, and the value of calculated length of members and the slenderness ratio are given also. The results can be referred in engineering practice.
