摘　　要：本文在综述穹顶网壳结构的基础上 ,提出了一种新型索杆预应力穹顶结构体系。该种结构具有杆件数量少、受力合理、建筑效果好等优点 ,同时具有较优的经济指标。文中对该种结构的受力性能作了计算分析 ,并与普通的网壳结构作了比较 。Based on a brief review of lattice dome strucutes, this paper presents a new cable bar prestressed dome system which has the advantages of aesthetically pleasing form, reasonable structural behavior and good economical index. The mechanical behavior of this type of structure is analyzed and compared with that for normal lattice shell structres. Results from this study can be used in practical design.
