| 摘 要： | 杂交空间结构系由不同类型的单一结构形式组合而成的空间结构体系,预应力全过程分析是其关键和难点。结合几类典型的杂交空间结构工程实践,详细讨论了不同结构形式中采用的预应力模拟和全过程分析方法,提出了初始形变迭代分析法、初始形变顺序分析法、升温降温法、模拟千斤顶法、影响矩阵迭代法等预应力分析方法,完善了杂交空间结构的预应力分析理论,并通过对实际工程的分析验证了这些方法的准确性。

| Abstract: | Hybridized space structure consists of different kinds of single structural types,in which the whole prestressing process analysis is the key and difficulty.Based on some species of typical hybridized space structures projects,the prestressing simulation and analysis methods in different kinds of structural types of hybridized space structures are discussed in detail.Some methods such as iterative method,sequential analysis method,increasing and decreasing temperature method,jack simulation method and influence matrix iterative method,etc.,are presented to perfect the prestressing analysis theory of hybridized space structure.Moreover,the methods are verified through analysis results of practical engineerings. |
