摘要
根据阻尼器的加载过程分析,提出了阻尼器耗散功率概念。对耗散功率谱法和传统滞回曲线法在评价阻尼器耗能能力方面进行了比较,特别在复杂加载情况下,耗散功率谱法具有显著的优点。通过对单调加载中因加载波形不同而导致耗能的变化的分析,提出了阻尼器耗能性能的综合评价方法。
Based on the analysis of damper movement during load test period, a concept for the dissipation power of damper is suggested. Comparing with the traditional method using hysteretic loop, the method of dissipation power seems obviously more useful when assessing the capacity of damper＇s power dissipation. After analyzing the difference of damper＇s energy dissipation, between two waveshapes of a simple loop load test, a comprehensive method for the capacity assessment of damper＇s power dissipation is suggested.
