【摘要】 空间管桁架结构越来越多的出现在人们的视野中,也是响应国家对于大型体育场馆的开发投资建设。该结构形式多出现在体育场馆的结构体系中,以天水体育中心为例,运用了基于光纤光栅传感器和振弦传感器在体育场的施工阶段的健康监测。本文将阐述此项目的健康监测系统的组成,监测方法以及测点布置等。分析监测数据表明:在施工阶段,各个关键杆件的应力变化稳定,杆件内力远小于钢材的屈服强度,各测点的应力状态始终处于弹性工作状态,满足了设计与施工的要求。更多还原

【Abstract】 The spatial tubular truss structure appears more and more in people’s eyes, which is also a response to the development and investment of large sports venues in China. The structure of the form appeared in the structural system of the venue, Tianshui sports center, for example, using and vibrating wire sensor based on fiber Bragg grating sensor in the stadium construction stage of health monitoring. In this paper, the composition,monitoring method and location of health monitoring system are described. Analysis of monitoring data show that in the construction phase, the key link of the stress change is stable, is far less than the yield strength of steel bar internal force, stress state has been the site of the elastic working state, meet the requirements of the design and construction.更多还原
