|
摘要
本文提出的新型软钢阻尼墙是一种设计新颖、耗能能力很强的剪切型金属阻尼器。给出了该新型软钢阻尼墙试件的构造形式。基于提出的加载方案对试件分别进行了基本性能试验和疲劳性能试验,分析了试件的滞回性能与疲劳性能等。试验结果表明该新型软钢阻尼墙具有稳定、良好的滞回性能和疲劳性能。采用ABAQUS软件对其建立了精细化有限元模型,并对其进行了有限元分析。数值仿真结果与试验结果很接近。这种新型软钢阻尼墙耗能性能优越,构造简单,且施工方便,有广阔的工程应用前景。
This paper presents a new shear-type mild steel damping wall,which is developed and designed at full-scale.In order to investigate the performance of the new shear-type metal damper,both basic performance test and fatigue test of the damping wall are carried out based on the given loading condition program in this paper.The constitutive model for the new damping wall is obtained from the experiment study.Experimental results indicate that the new mild damping wall possesses stable and effective energy dissipation capacity and excellent fatigue performance.A refined finite element model of the new mild damping wall is developed within environment of ABAQUS and the numerical simulation of the wall is then conducted in this paper.The numerical results match very well with the experimental data.The new mild steel damping wall is effective and convenient in construction,which may have a wide application prospect in the near future.
