9416484 Haroun The Northridge earthquake induced a number of incidents of damage to ground-based tanks, and even to some retrofitted tanks. Utilities and industrial facilities in the strong shaking area include a large inventory of tanks of all types, and many records have been obtained in the vicinity of damaged and undamaged tanks. The mass of data on earthquake ground motions and observations of the structural response have important implications for the earthquake resistant design. This is project will study the performance of tank structures as follows: Collection of data and documentation of the damaged sustained by ground-based water and petroleum storage tanks. Calculation of the dynamic response of representative tanks and correlation of the computed response with observed damage or lack of damage. Study of the effects of long period components on the sloshing phenomenon. Study of the damage to retrofitted tanks to deduce the reasons for the ineffectiveness of implemented to retrofit mechanisms. Specifically, a study of damage to the anchors is proposed to devise improved ways for the anchoring system. Comparison of induced seismic forces with those specified by available codes and standards such as API 650, AWWA 100, EPRI, UBC and the New Zealand Recommendations. New advances have been made in the analysis of liquid-filled tanks such as non-linear sloshing of liquids, elephant foot buckling of the tank shell, and combined liquid-structure-soil interaction. This is an opportune time to compare the predicted response with actual behavior under earthquake loading to refine and tune these methods and to provide improved seismic design procedures. This is a Northridge Earthquake project. ***

9416484 HAROUN北林地震造成了许多损坏地面坦克的事件，甚至造成了一些改造的坦克。 强大的摇动区域中的公用事业和工业设施包括各种类型的大量储罐，并且在受损和未受损的坦克附近获得了许多记录。 地震地面运动的数据质量和对结构反应的观察对抗震设计具有重要意义。 该项目将研究储罐结构的性能，如下所示：数据的收集以及地面水和石油储罐所损坏的文档。 计算代表储罐的动态响应以及计算响应与观察到的损害或缺乏损害的相关性。 研究长期成分对遗传现象的影响。 研究对改装储罐的损坏，以推断出对改造机制的实施无效性的原因。 具体而言，提出了对锚损伤的研究，以设计锚定系统的改进方法。 将诱导的地震力与可用代码和标准（例如API 650，AWWA 100，EPRI，UBC，UBC和新西兰建议）的比较。 分析充满液体液体的液体，液体倾斜，坦克壳的大象脚屈曲以及液体结构 - 土壤相互作用的分析，已经取得了新的进步。 这是将预测的响应与地震负载下的实际行为进行比较以完善和调整这些方法并提供改进的地震设计程序的时机。 这是一个诺斯里奇地震项目。 ***
