大连体育馆屋盖采用弦支穹顶结构。为保证屋盖结构在施工过程中以及以后使用中的安全，开发了屋盖结构健康监测系统。本文根据屋盖结构的受力特点，提出了详细的监测方案。光纤布拉格光栅传感器，倾角传感器，加速度传感器被用来测量必要的结构信息。为了实现对不同类型传感器的询问，本文还介绍了一种新型的结构健康监测系统数据采集装置，实现了多物理量的同步采集。通过对该体育馆在施工和正常使用过程中所获得的数据进行分析，对结构的健康状况进行评估，并对结构的损伤进行定位。
The roof of Dalian gymnasium was designed in the form of suspen-dome structure. A structural health–monitoring system has been developed for the roof structure to guarantee the safety condition during construction process as well as in future service. In this article, a monitoring scheme was proposed in detail according to the mechanical characteristics of the roof structure. Fiber Bragg grating sensors, inclinometers, and accelerometers were applied to measure necessary structural information. In order to interrogate different types of sensors, a novel data acquisition device of the structural health–monitoring system was also introduced and has achieved multitudinous physical variable synchronization acquisition. By analyzing the data obtained during the construction and normal operation of the gymnasium, the structural health condition was evaluated and the structural damage could subsequently be located.
