粘结性对圆钢管混凝土柱抗震性能的影响
|
摘要
通过对钢管混凝土柱粘结力的构成和地震作用下振动理论的分析,给出了有限元模拟中粘结力的实现方式,并使用有限元软件Ansys对两种不同粘结强度作用下的构件进行了模拟。模拟结果分析表明,粘结强度对构件的固有特性影响可忽略不计;在地震作用下,随着粘结强度的增强,钢管混凝土柱的振动位移逐渐减小,构件的地震加速度曲线呈现一定的规律性,说明钢管混凝土柱具有良好的耗能能力,且随着粘结强度的提高而逐渐增强。
Based on analysis of bond force formation of concrete-filled steel tubular column and vibration theory for seismic action,the implementing mode of bond force in finite element simulation was presented and simulation was carried out for components with two different bond strength by use of finite element software Ansys. Results show that the influence of bond strength on inherent characteristics of the components may be negligible,and in pace with enhancement of bond strength,vibrational displacement of the concrete-filled steel tubular column under earthquake action decrease gradually,the seismic acceleration curve of the component presents certain regularity. It means that the concrete-filled steel tubular columns possess a good energy dissipation capacity and it would be strengthened with increase of bond strength.
