摘要:
通信铁塔的地震易损性研究是通信系统震后灾害评估和预测的基础工作之一,但在以往的通信系统地震灾害评估研究中,这一工作被忽略了。在对北方某城市大量通信铁塔进行调研的基础上,选取了3个典型通信铁塔(50 m高四方塔、30 m高四方塔和50 m高单管塔)作为研究对象,采用有限元软件ABAQUS建立了数值模型;通过对3个铁塔的静力推覆分析,得到了处于不同损伤状态下的损伤指标数值;通过增量动力分析,得到了3个通信铁塔的抗震性能和地震易损性曲线,为通信系统地震灾害评估和预测提供参考。
Abstract:
As one of the basic works, the research on seismic vulnerability of communication tower is very important in seismic hazard evaluation and prediction of communication system. However, this part was ignored in the past. In this study, the information of communication towers in one city at north of China was surveyed. Based on these data, three typical communication towers (50 and 30 meters high square tower and 50 meters high single pipe tower) were chosen and their finite element models were established by the software of ABAQUS. Pushover analyses were performed on these tower and the values of damage indices corresponding to various damage states were obtained. Then, incremental dynamic analyses were performed for these towers and the seismic properties and seismic fragility curves were gotten. Seismic fragility curves of all the three communication towers will be used as the basic data in seismic evaluation and prediction of communication system in one area in north of China.
