非线性隔震立式浮顶储罐双向地震作用分析
|
摘要
研究浮顶振动对立式储罐地震响应的影响时,假定浮顶运动为均质刚性圆板振动,其波高沿半径方向线性变化,建立了含有波高参量的运动方程、基底剪力和倾覆力矩表达式。同时,在Park恢复力模型的基础上,给出了铅芯橡胶支座的双向耦合恢复力计算模型,并用该模型模拟了铅芯橡胶支座的力-变形非线性行为。采用时程分析方法对双向地震作用下的浮顶储罐地震响应进行分析,并与未考虑浮顶作用以及单向地震作用的储罐地震响应进行对比。数值结果表明,考虑浮顶作用具有降低地震响应的效果;特定工况下,地震响应峰值可能出现在非主震方向。
When study on the influence of the floating roof's vibration in vibration as on vertical storage tanks,we assume that the motion of floating roof is in vibration as a homogeneous rigid circular plate,and the wave height in the tank along the radius is changed linearly,then the equation of motion with the wave height parameter,and expression of base shear and overturning moment are established.Meanwhile,the two-way coupling restoring force model of LRB is given based on the restoring force Park model,and it is used to simulate the force-deformation nonlinear behavior of LRB.The seismic response of the floating roof tank under bi-directional excitation are analyzed using the time-history analysis method and compared with those of the tank under single excitation without considering the action of the floating roof.The numerical results show that the seismic response can be reduced if effects of floating roof are considered.In specific conditions,peak seismic response of the tank may not occur in the direction of main shock.
