大跨钢结构采光顶结构测试与分析

Structural monitoring and analysis for the large-span steel roof framework

介绍了浙江美术馆主屋盖钢屋架采光顶结构的测试,通过对结构测试仪器的介绍、结构测试方案的设计和测试数据的分析,得出使用振弦式传感器测试屋架钢梁结构的局部应变,从而获得钢梁端部结构应力的数据结果可行的结论,达到了施工期间结构测试要求。

An introduction for strain-stress measuring of the steel roof of Zhejiang art museum is presented. Through selecting measuring.instruments, designing measuring schemes, analyzing measuring data, local strain of the steel roof framework is obtained using vibrating-wire sensors. Stress of steel beam ends is calculated and the result shows that it meets the requirement to insure the safety of this steel framework.
