摘要
台州大学风雨操场索网膜结构工程是一个大型复杂整体张拉索网膜工程,有较大的技术难度.本文首先介绍了该工程新颖的索网结构体系、膜面找形,然后优化索膜预张力设计,深入结构分析,并阐述索膜关键节点设计,概要介绍安装过程和控制方法,最后研究索制造定位长度误差对索网膜预应力和形态的影响.
Cable-net membrane structure is one of the most advanced projects in the field of lightweight space structures in recent years in China.This paper firstly outlines the novel cable-net system and form-finding of cable-net and membrane.The prestress optimization are then carried out.And the structural analysis are performed comprehensively for various load cases.The joints and detail of some key cable-net connectors are depicted.The installation procedure and pre-stretching method are proposed for future use....
