2800mm非锚固金属储液罐大型地震模拟实验
|
摘要
为了研究大型石油储罐在地震载荷作用下的动态响应行为,对2800 mm非锚固圆柱形金属储液罐开展大型地震模拟实验。依托国内先进的地震模拟实验台,对实验用模型罐输入水平、竖直和多维组合方向地震激励来测试分析其地震动态响应行为规律,研究多种激励下,储液高度、有无浮顶、地震波幅值和频率等因素对模型罐动态响应行为的影响以及它们的联合作用,得到了不同工况下模型罐的绝对位移和提离响应行为规律。同时还系统地介绍了实验所选用的实验装备、模型罐、数据采集系统和地震激励的输入方法等情况。本实验的研究将为大型石油储罐抗震分析、结构设计和计算机数值模拟等提供可靠的数据。
A series of large earthquake simulation tests about the 2800 mm cylindrical large unanchored metal liquid storage tank models were taken to investigate the dynamic response behaviors of the large oil storage tanks under earthquake loads.Horizontal,vertical and multidimensional direction earthquake excitations were input respectively to the experimental model tank system to test and analyze the law of seismic response behavior on the advanced earthquake simulation test table.The effects of various factors,such as the liquid surface height,the floating roof,the different wave amplitudes and frequencies,as well as their combined effects to the seismic dynamic response were studied.The absolute displacement and the uplift response behavior law of the test models were obtained under different conditions.In addition,important factors in experiment were described systematically in this paper,for example,the experimental equipments,the tank models,the data acquisitions,seismic excitation input method and so on.Reliable basic data could be provided for the large oil storage tanks analysis on the earthquake-proof,structural design,computer numerical simulation research and so on through this investigation.
