FRP管约束混凝土柱抗侧向冲击能力实验

Experiment Research on Lateral Impact Bearing Capacity of FRP Pipe Confined Concrete Column

针对FRP管约束混凝土柱的抗侧向承载能力进行了系统研究,通过在FRP管约束混凝土柱的侧向施加静压载荷,对实验结果分析可知:在不同FRP管壁厚、纵横向纤维比例以及填充混凝土与否的情况下,FRP管柱以及FRP管约束混凝土柱试件呈现完全不同的破坏模式.由实验得出的应力-应变关系曲线和FRP混凝土柱所能承受的最大静压载荷数据,可以作为进一步对动态冲击下FRP混凝土柱的研究基础.

The lateral bearing capacity of FRP pipe confined concrete column is researched.Static pressure is applied on the lateral of FRP pipe confined concrete column,and the experimental results show that the failure modes of FRP pipe column and FRP pipe confined concrete column are totally different,when they have different pipe wall thickness,different fiber ratio of longitudinal and transverse and concrete infill or not.According to experiment,the stress-strain curves and the maximum static pressure which the FRP concrete column can afford can be used as the basis on researching FRP concrete column under dynamic impact.
