Study On Shaking Table Test Of100,000m~3Liquid-sotrage Tank Modal

Vertical float put the tank reserves flammable, explosive, toxic media facilitiesin the petrochemical industry, and once the earthquake damage, the consequencesare very serious. The seismic performance of tanks explore the key areas of thestorage tank seismic design. Over the years, research on ground motion show thatthe ground motion is multidimensional, multi-dimensional around shaking each toproduce coupling effects between Available above the reservoir seismic process,used by The seismic excitation, the reservoir of the seismic response analysis andexperimental research.This load form of incentive trial to explore the content closerto the actual situation of the storage tank seismic can provide a more reliable basisfor the storage tank seismic design.In this article,first introduced to the reservoir seismic study of the status quo athome and abroad, introduction of vertical storage tanks seismic research methods,and by contrast the pros and cons of various methods, and then select the10Articlesfloating roof storage tanks model (contains the ring wall foundation) shaking tabletest as the focus of this study. This study are as follows:1. introduce the test model (including the ring wall foundation) designmethodology, the relevant parameters of the shaking table test readiness.2. Given the shaking table test results, a brief trial phenomenon. White noiseexcitation the vibration characteristics of the obtained structure. Other waveformincentive analysis model in taking into account the coupling effect of the foundationand the upper tank test results, and draw some conclusions.3. Spectral transformation analysis on the part of the measuring pointacceleration in the test several input waveform obtained the internal model offloating roof in several waveform shaking difference, and given the differences inthe spectral range between three-and two-way shock.4. supplementary test of the model, including a simplified damping ratio test;the basis of differential settlement, analysis of the upper tank; model flush testanalysis in a certain speed bet fluid tank.5. Using general purpose finite element software ANSYS to model thenumerical calculation using the numerical simulation results to verify the test results.Relatively concerned about the test content in the test given by the simulation.Numerical simulation and experimental analysis for the seismic design of thevertical floating roof tank to provide a reliable basis. Finally, this articlesummarized the outlook based on this article study the contents of this article,...
