摘要

本文主要报道了一种基于无线分布式同步数据采集系统(WDSA)的摩天大楼在运行工况下的结构动力特性。首先,利用统一的全球导航卫星系统(GNSS)时间信息,方便地获取大型复杂结构的结构响应。通过比较有线中心数据采集(WCA)和WDSA系统估计的模态参数,验证了WDSA方法的相位同步精度。在此基础上,通过运行模态分析(OMA)对某摩天大楼的动态特性进行了分析。最后,进一步开发了基于WDSA的连续动态监测系统,以捕捉不同空间位置的长期结构响应。报道了该摩天大楼在正常风、台风和地震条件下的结构动力行为。在正常风和地震条件下,结构“鞭动效应”的特征是基于加速度的累积贡献因子。

Operational modal analysis and continuous dynamic monitoring of high‐rise building based on wireless distributed synchronized data acquisition system
The paper mainly reports the structural dynamic behaviors of a skyscraper under operational conditions based on a wireless distributed synchronized data acquisition (WDSA) system. First, the WDSA system is developed to conveniently acquire the structural responses from a large and complex structure with the unified Global Navigation Satellite System (GNSS) time information. The phase synchronization accuracy of the WDSA method is validated by comparing the modal parameters estimated by both wired central data acquisition (WCA) and the WDSA systems. Subsequently, the dynamic properties of a skyscraper are presented by performing operational modal analysis (OMA) based on the proposed WDSA system. Finally, the WDSA‐based continuous dynamic monitoring system is further developed to capture the long‐term structural responses at different spatial positions. The structural dynamic behaviors of the skyscraper under normal wind, typhoon and earthquake conditions are reported. The structural “whiplash effect” under both normal wind and earthquake conditions are characterized by the acceleration‐based accumulated contribution factor.
