本文通过数值模型对钢制储罐基础隔震效果进行了研究，并在1：14的真实钢制储罐缩尺模型上进行了振动台试验。在试验活动中，浮动顶板也被考虑在内。在物理模型上进行了固定和隔震基础配置的试验；特别是使用了两种可选的基础隔震系统：高阻尼橡胶支座装置和带弹塑性阻尼器的滑动隔震器。最后，将实验结果与数值计算结果进行了比较。版权所有©2009 John Wiley&Sons，Ltd.
In this paper, the effectiveness of the base isolation on steel storage tanks has been investigated through numerical models and then checked by shaking table tests on a reduced scale (1:14) model of a real steel tank, typically used in petrochemical plants. In the experimental campaign the floating roof has also been taken into account. The tests have been performed on the physical model both in fixed and isolated base configurations; in particular two alternative base isolation systems have been used: high‐damping rubber bearings devices and sliding isolators with elasto‐plastic dampers. Finally, a comparison between experimental and numerical results has also been performed. Copyright © 2009 John Wiley & Sons, Ltd.
