本文着重于卧式圆筒和立式圆筒压力容器的抗震分析和设计。首先，比较ASME B&PV规范和EN 13445-3中的抗震规定，对两个具体的案例进行研究，这两个案例构成了石油化工设施中使用的典型容器。此外，进行了数值研究，旨在提出一个可靠的值的行为系数为这些结构。这些问题进行了数值研究，模拟上述压力容器的非线性有限元模型。最后，概述了一种确定水平圆柱容器液体晃动地震力的方法。本研究的结果可用于在地震作用下更安全和更可靠的工业压力容器的设计。Kalliopi Diamanti，Ioannis Doukas和Spyros A.卡拉马诺斯2
The present paper focuses on the seismic analysis and design of horizontalcylindrical and vertical-cylindrical pressure vessels. First, a comparison of the seismic provisions in ASME B&PV code and in EN 13445-3 is conducted for two specific case studies, which constitute typical vessels used in pertochemical facilities. In addition, a numerical investigation is conducted, aimed at proposing a reliable value of the behavior factor for those structures. Those issues are examined numerically, simulating the above pressure vessels with nonlinear finite element models. Finally, a methodology for determining seismic forces due to liquid sloshing horizontal-cylndrical vessels is outlined. The results of the present study can be used towards a safer and more reliable design of industrial pressure vessels under seismic action. Kalliopi Diamanti, Ioannis Doukas and Spyros A. Karamanos 2
