本文使用概率方法评估了专为保护电信设备而设计的双圆锥滚动隔离系统的安全性。由于电信设备 GR-63-CORE 指南中输入加速度图的数量有限(只有一个),因此优化了八种不同的滤波器,以最好地捕获所需的响应谱。拟合的滤波器被纳入一个易于实现的框架中,该框架用于生成几套用于概率分析的加速度图。对这些分析的结果进行了分析和讨论,以揭示 GR-63-CORE 指南的缺点,通常是加速度图数量有限,并且忽略了规定加速度图中潜在重要的低频加速度。结果表明,规定的加速度图可能无法代表电信设备或保护它们的隔离系统预计会经历的激励,因此并不保守。此外,概率分析的结果以脆弱性曲线的形式呈现,可以指导滚动隔震系统的设计。
This paper assesses the safety of a double conical rolling isolation system designed for protecting telecommunications equipment using a probabilistic approach. Due to the limited number of input accelerograms in the GR-63-CORE guideline for telecommunications equipment (only one), eight different filters are optimized to best capture the required response spectrum. The fitted filters are incorporated into an easy-to-implement framework, which is used to generate several suites of accelerograms for the probabilistic analyses. The results of these analyses are analyzed and discussed to reveal the shortcomings of the GR-63-CORE guideline, which in general are the limited number of accelerograms and ignoring the potentially important low frequency accelerations in the prescribed accelerogram. It is shown that the prescribed accelerogram may not be representative of excitations that are expected to be experienced by telecommunications equipment or the isolation systems protecting them, and is, hence, not conservative. Moreover, the results of the probabilistic analyses are presented in the form of fragility curves that can guide the design of rolling isolation systems.
