| 摘 要： | 利用隔震储罐三质点力学模型,编程计算隔震储罐的地震反应,分析了隔震频率和阻尼对减震效果的影响.结果表明,采用适当参数的隔震基础,能够明显降低储罐的地震反应.在理想隔震频率范围内,隔震频率对储罐地震反应控制起主导作用,而阻尼的影响较弱,而且增大阻尼不一定降低储罐地震反应;当隔震频率大于6rad/s时,阻尼对地震反应的影响增强.

| Abstract: | The seismic response of seismic-isolated oil tank is calculated by three-particle mechanical model,and the influence of the seismic isolation frequency and damp on the vibration effect of oil storage tank is analyzed.It is shown that,the seismic isolation base of suitable frequency and damp can decrease the seismic response of the oil tank.In the range of ideal seismic isolation frequency,the influence of the seismic isolation frequency on the seismic response is dominant,the influence of the seismic isolation damp is little,and the increase of the damp cannot always decrease the seismic response;when the seismic isolation frequency is greater than 6 rad/s,the influence of the damp on the seismic response is increasing. |
