福州海峡国际会展中心扩建工程西区钢桁架施工过程监测

摘要

对福州海峡会展中心扩建工程西区钢桁架的施工过程进行监测.首先介绍了结构的受力特点、桁架施工方案和监测内容及测点布置方案;其次,对施工过程桁架的整体变形和弦杆应力进行了监测,并采用Midas-GEN软件进行数值模拟分析;测试结果表明,桁架的变形和应力值均在设计值允许范围内.%Construction monitoring of steel trusses was carried out for the expansion project of Fuzhou strait international conference exhibition western center.The stress characteristics of the structure and the construction scheme of the truss and monitoring contents and measuring points' arrangement were first introduced.Then,the overall deformation of trusses and the stress of components were monitored during the construction process.Numerical simulation analysis was also carried out by using Midas-GEN software.The test results show that the deformation and stress values of the trusses are all in the allowable designable values.
