高举架立式圆筒型储液容器基础隔震数值分析
|
摘要
目的通过对高举架立式圆筒型储液容器基础隔震数值分析,探究高举架储罐基础隔震的可行性.方法依据ACI简化力学模型提出分散支承质量简化力学模型的方法,并通过在其底部植入隔震层,建立基础隔震简化力学模型并推导其运动控制方程,采用数值方法对比分析了不同条件下地震动响应.结果 ACI简化法与分散支承质量简化法计算结果相近,说明笔者提出的分散支承质量简化力学模型是可行的;基础隔震能有效控制高举架立式圆筒型储液容器地震动响应;隔震周期和隔震层阻尼比越大,基础隔震减震效率越高.结论建议基础隔震设计时需根据工程实际情况选择最佳隔震层参数.
Through the numerical analysis of the base isolation elevated vertical cylinder storage tanks,the feasibility of base isolation is explored. According to the simplified mechanical model of ACI,the method of simplifying the mechanical model of dispersed bearing mass is proposed. By installing the isolation layer at the bottom the simplified mechanical model of the base isolation is established and the motion control equation is derived. The numerical method is used to compare and analyze the ground motion under different conditions. The calculation results of ACI simplification method and dispersed bearing mass simplification method are similar,which shows that the simplified mechanical model of dispersed support is feasible. The base isolation can effectively control the ground motion response of the vertical cylindrical storage tank. The longer isolation period and the larger damping ratio,the higher the efficiency of base isolation. It is suggested that the optimum isolation layer parameters should be selected according to the actual engineering condi-tions.
