摘　　要：着重分析了结构的最优矢跨比问题,分析了矢跨比对脊椎动物肋骨和钢结构临界载荷的影响,利用拱的屈曲理论,着重分析了脊椎动物肋骨的矢跨比,探讨了脊椎动物肋骨不是空间直线段而是空间拱形(矢跨比为0 25,在0 2和0 3之间)的力学机理.Emphatically analyzed problem on the best height_span ratio of a construction and the influence of that ratio on vertebrate rib and critical load of steel construction.Using the crook theory for an arch,we stress on analysing the height_span ratio of vertebrate rib,and approaching mechanical mechanism of the fact that vertebrate rib is not a space straight line segment but is a space arch form.

关 键 词：矢跨比 稳定性 临界载荷 脊椎动物肋骨 钢结构
