|
摘要
对钢制的大型带外浮顶的圆柱形储液罐模型进行振动台模拟试验,通过在不同工况下,对试验结构系统输入水平和竖直两种方向地震激励来测试和分析其地震响应情况,得到两种激励方向下,储液高度、有无浮顶情况、地震波幅值和频率等各种因素对模型结构系统动态响应行为的影响以及它们的联合作用,并得到各种工况下本试验模型结构系统的绝对位移和提离响应行为规律。此外,还系统地阐述了试验中所选用的实验台设备、试验方法、罐体模型设计、传感器、数据采集、测点布置方法和地震激励的输入方法等试验中的重要因素。本试验的研究将为理论分析、结构设计和计算机数值模拟等研究项目提供可靠的依据。
A series of seismic table tests about the large steel cylindrical liquid storage tank models with floating roof were taken. Horizontal and vertical direction seismic excitations were input respectively to the experimental structure system under different working conditions to test and analyze the seismic response behavior. 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 got. The absolute displacement and the uplift response behavior law of the test models were obtained under different conditions. The conclusion was gain that not only uplift value but also the absolute displacement of the tank bottom should be considered. And it should be noticed that a critical input frequency exists during the model response changing with frequency. In addition,important factors in experiment were described systematically,for example,the experimental equipment selection,the experimental method,the tank model design,the laser displacement sensors,the data acquisition,the measurement point layout method,seismic excitation input method and so on. A reliable basis could be provided for theoretical analysis,structural design and computer numerical simulation research through this investigation.
