Suspendome is a new hybrid space structure, composed of cablestrut tensile structure and single reticulated shell. In this paper, the initial prestress distribution and the static stability of suspendome was analyzed. A new method named local analysis method is first presented and adopted where the whole structure is divided into two parts: the upper structure and the lower structure. Combining the topological relation of suspendome, it can be used to simplify the distribution of initial prestress. Then the static stability of this kind of structure was investigated by the geometrical nonlinear finite element method. Compared to the single reticulated shell, although its steel quantity increases by 30 percent, its critical load improves 266 percent. And the structural system of suspendome is more rational and has a very good applied perspective.  弦支穹顶结构体系是基于索杆张力体系和单层网壳而形成的一种新型杂交空间结构体系.本文对这种结构的初始预应力确定方法及其稳定性能进行了深入的理论研究.提出并采用了基于将结构分块的分析方法——局部分析法,并结合弦支穹顶的拓扑关系对初始预应力分布的确定进行了简化.针对联方网格型弦支穹顶结构进行了静力稳定性能分析,结果表明同单层网壳相比,尽管其用钢量增加了近30%,但其极限载荷却提高了266%,结构体系更加合理,具有很好的应用前景.

However, theoretical analysis of this kind of structures has not been well established. Some problems in the design and construction of beamstring structures are presented and discussed including the prestress distribution of each element corresponding to the initial geometry and the simulation of construction process. First, the equilibrium matrix theory is extended to the analysis of hybrid spatial structures composed of beams, bars and cables and a general form of the equilibrium matrix of twonode beam element and bar element is also derived. Using its total equilibrium matrix, a small beamstring structure is analyzed and only one independent selfstress mode is obtained. Secondly, another method, named as local analysis method, is presented where the whole structure is divided into two parts: the upper structure and the lower structure. It can also be used to obtain the initial prestress distribution and the zerostate geometry of the upper structure. Numerical examples are given to verify the methods.  张弦梁(桁架)结构已在我国大型工程中有所应用,但对该种结构的设计和施工过程的理论研究并不完善。对张弦梁结构设计和施工过程中的若干问题进行了较为深入的理论研究,包括该结构各个单元的预应力分布、施工过程的模拟分析等。首先,将平衡矩阵理论推广应用于包含索杆梁三种单元的杂交空间结构,给出了二节点梁单元和杆单元单元平衡矩阵的一般表达式,并对一小型张弦梁结构的整体平衡矩阵进行了分析,求得其独立自应力模态数为一。其次,提出了基于将索、杆单元和梁单元分开的结构分块的分析方法局部分析法。该方法不仅可以用来求解张弦梁结构的初始预应力分布,同时也可以用于确定体系的零状态几何形状。因而求解张弦梁结构初始预应力分布就有了两种方法。最后,算例分析验证了方法的正确性。
