中文摘要：
阶梯式肋环型球面网格结构是一种新的结构形式，具有较强的建筑表现力，其结构性能介于单、双层网壳之间，具有较好的稳定承载力．通过对不同矢高的阶梯式肋环型球面网格结构的静力参数分析，得到了这种结构的基本性能特点与传力规律．通过动力特性分析，反映了结构基本的刚度分布规律．稳定性分析是壳体结构必须进行的计算，通过线性特征值与非线性极限稳定性分析计算了此类结构的失稳模式与极限承载力，从而较为全面地分析了这种结构的结构性能，得到了一些有意义的结论．
英文摘要：
Ladder form rib-ring type of spherical latticed shell is a new structural system with a strong architectural expression. Its structural performance may be between that of single-layer and double-layer latticed shell and it has a good stability bear capacity. In this paper, the basic static performance characteristic of this structure is presented according to the parameter analysis by using different model with different rise-to-span ratio. Through the dynamic analysis, basic stiffness distribution of the structure is investigated. Linear-eigenvalue buckling analysis is also carried out. The instability mode and ultimate bearing capacity are researched in accordance to the nonlinear load analysis. Some meaningful conclusions are obtained.
