中国航海博物馆中央帆体结构为新型杂交结构,其最大亮点是位于东西帆体之间的双曲面单层索网幕墙.这是世界上首例支承在弹性边界上的双曲面单层索网玻璃幕墙,其设计与施工存在较大的技术难度.为验证索网成形和张拉施工过程可行性,进行了双曲索网结构的缩尺模型试验.本文系统比较不同张拉方案的优劣性,分析试验结果,发现施工张拉中可能出现的问题并提出解决方案.
China Maritime Museum Central sail body structure as a new hybrid structure, the highlight of which is located between the body of the sail between the hyperbolic single-layer cable network.This is the world’s first support on the elastic boundary of the hyperboloid single-layer cable mesh Curtain wall, its design and construction there is a big technical difficulty.In order to verify the feasibility of cable network forming and tensioning process, the hyperbolic cable network structure scale model test.This paper systematically compares the advantages and disadvantages of different tensioning scheme , Analyze the test results and find out the problems that may appear in the construction tension and propose solutions.
