本文主要做了以下几个方面的工作：1、利用GPS等多种传感器，建立了广州新电视塔的健康监测系统；2、采用一种仅基于输出响应的模态识别算法（频域分解法），结合台风期间所测得的加速度响应识别了广州新电视塔的前十阶模态参数；3、用图、表和有限元模型描述了电视塔的在台风期间的形变状态，揭示了其动力特性。具有理论创新和较好应用借鉴作用。

The main outcome of this paper include the followings: First of all, a structural health monitoring (SHM) system consisting of various sensors (including the GPS et al.) is being implemented to the Guangzhou New TV Tower (GNTVT). Secondly, making use of an output-only modal identification algorithm (Frequency Domain Decomposition-FDD), the first ten modal parameters of GNTVT are identified using the measured acceleration responses acquired during the typhoon periods. Finally, the structural responses and dynamic characteristics during the typhoons are presented by using figures, tables and finite element model. The results of this paper have dual meanings of theory innovation and practice instruction.
