摘要:
关键移动通信设备的地震易损性是城市移动通信系统地震灾害预测的基础。本文以移动通信系统节点机房中常用的蓄电池组作为研究对象,通过振动台试验来研究蓄电池组的抗震性能,并获得其地震易损性。试验过程中,首先采用FEMA P695建议的方法从美国PEER强震数据库中遴选出对蓄电池组较为危险的地震动记录作为试验激励,随后逐步增大各条地震动记录的幅值,基于振动台进行增量动力分析。试验后根据蓄电池组的地震损伤特征,定义了其损伤指标和损伤水平,并基于振动台试验数据分析获得了典型蓄电池组的地震易损性曲线。
Abstract:
The seismic fragility analysis of the important mobile communication equipment is a basic work in predicting the seismic disaster of the mobile communication system after earthquake. In this study, the storage batteries commonly used in the node computer room of the mobile communication system were investigated. The seismic performance of the storage battery was studied by shaking table test, and its seismic vulnerability curves was obtained. During the test, six earthquake records were selected from the PEER strong earthquake database as the earthquake excitations according to the method in FEMA P695. Then the amplitude of each earthquake record was gradually increased. The incremental dynamic analysis was carried out by using the shaking table. After the test, the damage index and damage level were defined according to the seismic damage characteristics of storage battery. Based on the shaking table test data, the seismic fragility curve of the typical storage battery was obtained.
