粘弹性阻尼结构减震效果的统计分析与算法比较
Statistical Analysis and Analytical Method Comparison of Structure with Added Viscoelastic Dampers
【摘要】 采用复模态方法、强解耦振型分解反应谱法和模态应变能方法分别计算结构的地震响应,并对计算结果进行统计分析,得到粘弹性阻尼器在框架结构中的减震效果的分布规律,可以为工程应用提供参考;并比较了复模态方法、Wilson-θ法、强解耦振型分解反应谱法和应变能方法的差异。
【Abstract】 Complex mode method,forcing decoupling response spectra method and modal strain energy method are employed to calculate the earthquake response.A statistical analysis of above-attained results are made.Damping effectiveness and damping ratiodistributed rule of viscoelastic dampers (VED) are obtained,which can provide suggestion for engineering.Furthermore,differences among complex mode method,Wilson-θ method,forcing decoupling response spectra method and modal strain energy method are pointed out.
