摘　　要：从理论上探讨了软钢阻尼器发挥最佳减震效果时结构应具备的条件。首先基于等效粘滞阻尼比的定义,推导了软钢阻尼器结构等效粘滞阻尼比的表达式,据此,进一步确定了结构等效粘滞阻尼比取最大值时的阻尼装置受剪承载力分配率,将其定义为最优分配率,从而明确了使软钢阻尼器的耗能量达到最大时软钢阻尼器结构所应具备的条件。This paper studies the condition that structures should be in when hysteretic dampers mitigate seismic action most effectively in theory. First, based on the definition, the formula of equivalent damping ratio of the structure with hysteretic dampers is derived. Hereby, the strength ratio of the damper system is ascertained as the equivalent viscous damping ratio is maximum, which is defined as the optimum strength ratio. Accordingly, the condition of structures that hysteretic dampers dissipate most energy is definite.

关 键 词：软钢阻尼器 等效粘滞阻尼比 最优分配率 耗能
