纤维复合筋增强混凝土的抗震性能试验研究

Experimental Study on Seismic Performance of Fiber-reinforced Composite Bars Reinforced Concrete

为探究不同纤维材料的纤维复合筋增强混凝土抗震性能,采用碳纤维材料、玄武岩材料、玻璃纤维材料制作6个纤维复合筋增强混凝土试件,实验设计拉伸装置及荷载加载装置,对3种类型的纤维复合筋增强混凝土试件进行地震受力模拟,分析其极限承载力情况。三种纤维的复合筋增强混凝土的极限承载力,由大到小排列为:碳纤维>玄武岩纤维>玻璃纤维,相对比玄武岩纤维与玻璃纤维的复合筋增强混凝土,碳纤维复合筋增强混凝土试件的极限承载力,增加了14.26%与18.56%。三种纤维的复合筋增强混凝土的极限承载力情况为:碳纤维>玄武岩纤维>玻璃纤维,碳纤维的极限承载荷载最高,具有较好的抗震性能。

In order to explore the seismic performance of fiber-reinforced concrete reinforced with different fiber materials,six fiberreinforced concrete specimens were made using carbon fiber materials,basalt materials,and glass fiber materials.The tensile device and load loading device were experimentally designed.Three types of fiber-reinforced concrete specimens were subjected to seismic stress simulation and their ultimate bearing capacity was analyzed.The ultimate bearing capacity of concrete reinforced with three types of fiber composite bars is arranged in descending order:carbon fiber>basalt fiber>glass fiber.Compared to the composite bars reinforced with basalt fiber and glass fiber,the ultimate bearing capacity of concrete specimens reinforced with carbon fiber composite bars has increased by 14.26%and 18.56%,respectively.The ultimate bearing capacity of reinforced concrete with three types of fiber reinforced composite bars is carbon fiber>basalt fiber>glass fiber,with carbon fiber having the highest ultimate bearing load and good seismic performance.
