RESEARCH ON STRENGTHENING TECHNOLOGY OF LONG-SPAN RETICULATED SHELLS
-
摘要: 对联方型网壳结构的主要特点给予介绍,并通过一个联方型网壳结构的工程实例,指出网壳结构进行加固改造的原则。根据结构验算结果,得出该大跨度网壳结构目前主要存在的问题。比较不同的加固方案,得出采用碳纤维布加固法是对网壳结构较理想的加固方法,该加固方法可以为同类加固工程提供参考经验。Abstract: The main characteristics of lamella reticulated shells are introduced in this paper. According to an engineering example of lamella reticulated shells, the principle of strengthening is indicated for reticulated shells. Based on the results of structural calculation, the main problem is gained for the long-span reticulated shells. Carbon fiber sheet strengthening method is a perfect strengthening method for reticulated shells as comparied with other strengthening methods. So the method could offer experience for the similar strengthening projects.
