| 摘 要： | 特大型液化天然气(LNG)储罐的固有频率通常介于2～10Hz之间,处于大部分地震运动的频率范围之内.在过去的几十年中,许多事故已经证明,储罐在地震作用下很容易遭破坏.使用隔震支座来减少储罐的地震作用已经被证明是非常有效的,但对于特大型LNG储罐,其连接组件对隔震层层问位移有严格限制,尤其是在软土场地中,桩水平抗力与隔震...

| Abstract: | Most of the large liguified natural gas(LNG) tanks have a fundamental frequency between 2 and 10 Hz which involves range of resonant frequency of most earthquake ground motions.In the past few decades,many accidents happening in earthquakes proved that the tanks could be damaged easily by earthquakes.It is an effective way to reduce the response of storage tank by use of isolation system in strong earthquake.However,there is a strict restriction of connection component on interlayer displacement of isolatio... |
