摘要
克服强行解耦法(FD)不能求解对称结构由于不对称安装粘滞消能器而产生平扭耦合地震作用的不足,提出了一种求解该种情况下的平扭耦合地震反应的新方法———两步附加刚度法(TSAS).此外,在理论分析的基础上进一步提出了中低层对称结构不对称安装粘滞消能器时的实用抗震设计方法,推导出了相应的平扭耦合地震作用的计算公式.
Overcoming the inability of Forcing Decoupling method ( FD), this paper presents a new method -Two-Step-Additional-Stiffness method (TSAS) to calculate the translation-torsion coupling seismic response of the symmetric structures with asymmetrically viscous dampers. Furthermore, this paper develops a practically seismic design method of the middle-rise or low-rise symmetric structures with unsymmetrically viscous dampers on the basis of the theoretical analysis and provides corresponding formulas to obtain the translation-torsion coupling seismic response
