Abstract
Selected the two kinds of mechanical models ,Housner model of rigidity theory and the theory of flexible Haroun-Housner model ,Housner model is simplified to two particle structure ,Hauroun Housner model simplified into three particle structure ,algorithm and its specification frequency comparison ,the fi-nite element algorithm ,error less than 5%.By using Newmark -beta elastic time history analysis ,get the liquid displacement time history ,acceleration time history of each particle and the tank bottom shear cal-endar ,overturning moment .The simulation results show that the simplified model and finite element algo-rithm of frequency of the code , a small , late horizontal earthquake excitation , the rock particle displace-ment time history is large ,rigid pulse particle displacement time history almost unanimously ,tank bottom shear algorithm of the code and is very small ,overturning moment is large .Housner method design of liq-uid storage tank ,the liquid sloshing part of the response is undervalued ,storage tank engineering design-ers and researchers should attach importance to it .关键词
