　　由于有限元仿真需要假设材料性能，难以真实全面地反映储液罐的地震响应；而振动台试验只能完成较小比例的模型试验，与储罐原型差距很大。为此，提出了储液罐子结构振动台试验方法，采用 Malhotra 力学模型，将储液罐划分为试验子结构和数值子结构两部分。运用 MATLAB 程序对储液罐子结构振动台试验进行了仿真试验分析。仿真计算表明：储液罐子结构仿真结果与全结构的计算结果有较好的吻合性，仿真计算的储罐基底剪力与规范算法接近。

It is difficult to truly reflect the seismic response of the liquid storage tanks by the finite ele -ment simulation due to simplification of material properties .And the shaking table can only complete small scale model tests,the obtained results may quite different with what of the tank prototype .To this end,a method of the liquid storage tanks substructure shaking table test was proposed ,using the Malhotra simpli-fied model,the liquid storage tank is divided into two parts i .e.the experimental substructure and the nu -merical substructure.MATLAB program is used to simulate and analyze the liquid storage tank substruc -ture shaking table test.The results are in good agreement with what of the whole structure .The obtained tank base shear force is close with what of the specification algorithm .
