【摘要】 中放废液收集槽是大型立式储液容器。为考虑容器内液体的晃动效应,引入三维的质量-弹簧模型,用响应谱分析的方法研究模型在地震作用下的响应。结果表明,把质量-弹簧模型引入到三维模型中是有效的方法;结构的最大应力出现在容器与支腿交界处。更多还原

【Abstract】 Collection tank for middle level radioactive waste liquid is a large standing liquid tank. Considering the fluctuant effect of the liquid, the 3D mass-spring finite element model is applied. The response under the earthquake were calculated by means of response spectrum analysis. The results show that the mass-spring model referenced to 3-D model is effective and the maximum stress concentration of the structure appears at the junction of the tank and the leg.更多还原
