的力学性能研究
摘要
纤维强化聚合物（Fiber Reinforced Polymer. FRP），是以纤维强化聚合物基质的复合材料，凭借着轻质量、高强度、耐腐蚀能力强、施工方便等众多优点，在土木工程领域逐渐得到认可。本文结合BFRP（Bamboo Fiber Reinforce Polymer）约束混凝土柱在国内外的研究现状，主要针对其在轴压状态下的力学性能进行综述，通过总结他们实验的优点和研究上存在的不足，提出竹纤维复合材料和约束混凝土柱的课题，在不同纤维包裹层数、混凝土强度等级等参数变化条件下，研究BFRP复合管约束混凝土在不同约束条件下的轴压力学性能。

Abstract
Fiber Reinforced Polymer (FRP) is a composite material based on fiber reinforced polymer matrix, which has been gradually recognized in the civil engineering field due to its advantages of light weight, high strength, corrosion resistance and convenient construction. In this paper, the research status of the confined concrete columns at home and abroad based on the Bamboo Fiber Reinforce Polymer (BFRP) is reviewed. The mechanical properties of the concrete columns under axial compression are summarized. By summarizing the advantages and disadvantages of the experiments, Materials and constrained concrete columns, the axial compressive mechanical properties of BFRP composite confined concrete under different restraint conditions were studied under the conditions of different fiber wraps, concrete strength grades and other parameters.
