大型空间结构整体模型静力试验的若干关键技术
|
摘要
本文结合上海大剧院钢屋盖、上海体育场马鞍型屋盖、上海浦东国际机场候机楼钢屋架、上海国际会议中心单层球网壳等整体模型试验 ,从结构模型、加载装置、测点布置、数据采集与分析等方面阐述了大跨空间结构整体模型试验的若干关键技术 ;并据此提出了整体模型试验与节点试验、动力试验、结构试验理论、空间结构仿真分析等的相关技术问题。
Some static tests of overall model of super spatial structures are performed in Shanghai. These are steel roof structure of the Shanghai Great Theater, spatial saddle?shaped roof of the Shanghai Stadium with 80,000 seats, roof truss of the Pudong International Airport, and single?layer dome of the Shanghai International Convention Center. Some key technics are summarized from the test results. Model design, loading, instrument set up, and data acquisition and analysis for an overall model test are considered in the paper. The interaction between overall model test and full?scale joint test, dynamic test, experimental theory, simulation for a spatial structure is also discussed.
