摘要
研究了某大型圆柱形薄壁储液罐在地震作用下的响应。采用基于Housner(1957)和Velet-sos(1973)两种理论的附加质量法计算流体的动压力。发展了附加质量法用户子程序,将其嵌入有限元软件ABAQUS进行计算。文中还将附加质量法的结果与ABAQUS耦合欧拉-拉格朗日算法(CEL)进行了比较,从而为该附加质量法的适用性提供了定性评估。
Responses of a large - scale cylindrical thin - wall liquid - storage tank under seismic excitations are studied. Added mass approaches based on Housner （1957） and Veletsos （1973） theories are used to compute liquid＇s dynamic pressure. User subroutines for these added mass approaches are developed and implemented into finite element code ABAQUS. Furthermore, results from added mass approaches are compared with that from ABAQUS Coupled Eulerian - Lagrangian （CEL） analysis. Therefore, an evaluation of the added mass approaches used in this paper is carried out
