| 摘 要： | 将消能减震概念应用于非结构构件,提出一种屈服耗能隔墙。该隔墙在小震下为主体结构提供可量化的刚度支持,大震时提供可调节的耗能能力支持。通过对屈服耗能隔墙试件进行不同耗能元件数量下的静力往复试验,研究了该类型隔墙的消能机理与破坏模式,并基于IDARC程序中的柱单元对试件进行模拟,获得了消能元件数量与隔墙滞回参数之间的量化关系,提出了在IDARC程序中模拟设置屈服耗能隔墙的方法。通过对一个6层钢筋混凝土框架进行不同屈服耗能隔墙设置方案下的动力时程分析,发现屈服耗能隔墙的设置能够有效减小结构的地震反应、降低结构的损伤;框架中耗能隔墙数量的增加会使结构的层间位移显著减小,而隔墙数量相同时,隔墙中耗能元件数量的增加并不会导致结构层间位移发生明显变化。

| Abstract: | By applying the ideal of energy dissipater to nonstructural components,yielding energy dissipation partition (YEDP) was proposed.The YEDP could provide quantifiable stiffness under minor earthquakes and adjustable energy dissipation capacity under major earthquakes.The static cyclic loading tests of YEDP with different number of energy components were completed,and the energy dissipation mechanism and failure mode of YEDP were got understanding.Based on the quantitative relationship between number of energy components and hysteresis curve parameters,the method which using column unit of IDARC program to simulate YEDP was proposed.The dynamic time-history analysis of 6-storey reinforced concrete frame under different YEDP set programs were carried out,the results show that YEDP could effectively reduce the seismic response of the structure.The interlayer displacement of structure decreases significantly with the increasing of number of YEDP,but be changeless with the increasing of number of energy components in the YEDP when the number of YEDP is same. |
