球型支座应用于大型渡槽的隔震研究
|
摘要
结合实际大型渡槽工程,设计球型隔震支座NKQZ15000GD,该支座具有较高的竖向承载能力、较低的水平剪切刚度,并具有一定阻尼和复位能力;对该支座进行材料性能测试,拟合支座的力学性能参数;分别采用反应谱法和动力时程法,计算隔震渡槽在设计地震与超设计地震作用下的动力反应;分析球型隔震支座应用于大型渡槽的减震效果,根据定量分析的结果得到一些规律性的结论。
For the actual large-scale aqueduct project,a ball isolation bearings NKQZ15000GD was designed,which showed a higher vertical bearing capacit,lower shear stiffness,certain damping and reset capability.Material testing was conducted on the bearings and the mechanical parameters were obtained by test data fitting.The response spectrum method and dynamic time-history method were used to analyze the seismic responses of isolation aqueduct under the designed earthquake and super-designed earthquake.Damping effect of the ball bearings set in the large-scale aqueduct was also analyzed.According to the results of quantitative analyses,some regularity conclusions were given.
