项目摘要
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北岭地震导致了一些地面坦克的损坏事件,甚至一些改装的坦克也受到了损坏。 强震动区域的公用事业和工业设施包括各种类型的储罐的大量库存,并且在受损和未受损储罐附近获得了许多记录。 大量的地震动数据和结构反应观测对抗震设计具有重要意义。 本项目将研究储罐结构的性能,如下所示: 收集受损害的国家的数据和文件 地面储水罐和石油储存罐。 典型储罐动态响应计算 以及计算响应与观测损伤的相关性 或者没有损伤。 长周期分量对液体晃动影响的研究 现象 对改装后油罐损坏原因的分析 对于执行的改造机制的无效性。 具体而言,建议对锚的损坏进行研究, 为锚定系统设计改进的方法。 诱发地震力与 可用的规范和标准,例如API 650,AWWA 100,EPRI, UBC和新西兰建议。 充液贮箱的非线性晃动、箱壳象足屈曲、液-固-土耦合等问题的研究取得了新的进展。 这是一个比较预测的反应与地震荷载下的实际行为,以完善和调整这些方法,并提供改进的抗震设计程序的适当时机。 这是一个北岭地震项目。 ***
