摘要
本文基于应变能概念,从附加等效阻尼比计算的基本理论出发,结合国内外相关规范、导则及论文,讨论了几种计算附加非线性黏滞阻尼器建筑结构的附加等效阻尼比实用估计方法。以一个实际工程为算例,比较附加黏滞阻尼器结构和两种不同估计方法得到的附加等效阻尼比的阻尼结构在地震时程下的响应,验证了各方法计算结果满足工程精度情况。
On the basis of the concept of strain-energy method, with the basic theories of calculation for e- quivalent damping and the combination of related codes, guide rules and papers of domestic and abroad, several practical methods were discussed which were used to estimate the additional damping of structure with nonlinear viscous dampers. Through a practical engineering project, the responses with viscous damper model and the one with additional damping ratio model were compared under earthquake time-hi- story, which verified that the results of the methods of calculation for equivalent damping ratio satisfy the engineering precision.
