摘要
本文提出了一种新的储液罐提离计算模型。这种计算模型考虑了罐底板以及地基的柔性。算例表明,用这种计算模型算出的罐底板的提离区域呈新月形,这与文献中的试验结果一致。因此,本文提出的计算模型较现有各种模型更为合理和符合实际。
A new computational model for the dynamic uplift analysis of liquid storage tanks is presented. It takes into consideration the flexibility of the tank base plate and its dynamic interaction with the foundation. The result of numerical examples reveals that the calculated uplift part of the base plate is crescent in shape, which agrees well with the experimental result given in the literature. Therefore, in comparison with the currently available methods the proposed computational model appears more rational and agrees more appropriately with the reality.
