带黏滞减震层高层结构的优化分析
|
摘要
对带黏滞减震层高层结构进行地震作用下的非线性动力时程反应分析,研究结构的顶层位移、基底剪力、减震层中阻尼力与主体结构层间剪力分配关系的变化规律;采用积算公式和减震层阻尼力比公式对减震层的位置、数量和黏滞阻尼器的参数进行优化分析,给出带黏滞减震层高层结构的优化设计方法,并对一个工程实例进行减震效果的优化设计。研究结果表明:当设置单道黏滞减震层时,减震层布置在结构的中部对顶层位移的减小效果较好,布置在结构的上部对基底剪力的减小效果较好;当设置多道黏滞减震层时,可采用积算公式对多道减震层布置位置和数量进行优化;当减震层位置确定后,可采用减震层阻尼力比公式对各减震层的黏滞阻尼器参数进行快速估计和优化;给出的带黏滞减震层结构的优化设计方法有效、实用,可供实际工程参考使用。
Based on nonlinear time history analysis,top floor displacement,base shear,and the relationship between damping force and story shear of the main structure in viscous energy-dissipation story were investigated.By product algorithm formula and damping force ratio formula,the position and quantity of energy-dissipation stories and parameters of viscous dampers were optimized.An optimization design method was proposed and used in an engineering project.The results show that if single energy-dissipation story is fixed on the middle of structure,the effect on reducing top floor displacement is good,and fixing on the upper of structure can produce good effect on reducing base shear.Product algorithm formula could optimize the position and the quantity of multi-energy-dissipation stories,and damping force ratio formula can be used to estimate and optimize parameters of viscous dampers.The proposed design method can provide reference for structures with viscous energy-dissipation story.
