摘要

准确地估算附加等效阻尼系数对于黏滞阻尼器减震结构的设计具有实用意义。该论文从线性化基本理论出发,通过阻尼器-结构耦合关系分析,提出一种基于全过程迭代和耗能相等的等效阻尼系数计算方法。计算方法物理意义明确,同时考虑了黏滞阻尼器自身参数和结构动力响应对等效阻尼系数的影响,且迭代过程具有收敛速度快、计算精度高等优点。该论文通过对多个算例的地震响应分析,并与精细化方法进行对比验证了该计算方法的可靠性。

Abstract

Accurately estimating additional equivalent damping coefficients is foremost for designing structures with viscous dampers.Based on the linearization theory and damper-structure coupling analysis, an estimation method was proposed by applying the inter-history iteration and energy dissipation equivalency.The proposed method exhibits clear physical meaning, with full consideration of the influence of both damping parameters and structural dynamic responses.Moreover, it also has a fast convergence speed and high accuracy.The reliability of the proposed method was validated by the simulations of several case studies and the comparison with an accurate method.
