弹性曲弯网壳是由平面网格变形而来,其节点形式采用了叠合式连接方式,这种特征导致其结构的建造与传统网壳施工有很大差别。文章对弹性曲弯网壳两种常用施工模式包括项升法和沉降法的各自特点分别作了深入分析并与高空散装等传统网壳建造方法作了横向对比,同时揭示了弹性曲弯施工这种非常规空间结构建造方式中的生态可持续发展理念。
Bent-up construction technique as one novel method to build grid shell is much different from traditional construction way, the shell is built with great deformation from original flat grids and all the members are connected by superposition joists. In the paper, wards" and "downwards" for grid shell construction characteristics of two typical bent-up modes as "upare analyzed and compared with conventional spatial structure construction way on the basis of ecological concept of sustainable development
