Experimental and Analytical Study on Channel Shear Connectors in Fiber-Reinforced Concrete(FRC) 纤维钢筋混凝土(FRC)结构中槽钢剪力连接件的试验和分析研究
The bending fatigue damage behaviors of a new kind of material & steel fiber-reinforced and polymer-modified concrete was experimentally and theoretically investigated, and the results were compared with those of steel fiber-reinforced concrete. 对钢纤维增强聚合物改性混凝土这种新材料的弯曲疲劳损伤特性进行了试验和理论研究,并且和钢纤维增强混凝土进行了对比。
Nowadays, the fiber-reinforced concrete becomes one of the research focuses for its superior mechanical properties. 纤维混凝土由于其优异的力学性能而成为当前研究的一个热点。
Therefore, the research and analysis of characteristics and master concrete structure state are very necessary for PVA fiber-reinforced concrete material. This paper put forward by use of the acoustic emission monitoring the damage evolution process. 因此研究和分析PVA纤维混凝土材料的特性并掌握混凝土结构状态是非常必要的,本文提出采用声发射技术监测其损伤演化过程。
