| 摘 要： | 通过在钢结构模型楼层设置软钢阻尼器，采用质点系模型和自编时程分析法程序，讨论了阻尼器设置参数与楼层动力响应值减震效果之间的关系，分别研究了楼层和阻尼器的塑性能与阻尼器有效刚度之间的关系．结果表明：层间最大位移角的减震效果最好，且有控楼层要好于无控楼层；最大速度和最大加速度的减震效果与阻尼器设置参数、输人地震动有关；随着阻尼器有效刚度的增大，有控楼层的楼层最大剪力降低，楼层的塑性能减少，阻尼器的塑性能增多且幅度下降．

| Abstract: | Based on the mass-system model and time-history analysis program,the relation between setting parameters of dampers and mitigation effect of storey dynamical response was discussed by setting mild steel dampers in floors.Furthermore,plastic energy of floors and dampers with dampers effective stiffness were studied separately.The results indicate that the mitigation effect of maximal inter-laminar displacement angle is best,and controlled floor is more obvious than uncontrolled one.The mitigation effect of m... |
