采用高性能纤维增强复合材料对混凝土柱进行加固,可有效地提高混凝土柱的承载力和延性。本文利用碳纤维和芳纶纤维分别对混凝土圆柱进行加固,研究了高性能纤维补强混凝土圆柱的力学性能,全面分析了承载力的变化以及应力与应变的关系。试验表明:纤维增强复合材料对混凝土柱具有优异的约束性能,经补强后的混凝土圆柱的承载能力大幅提高。
The use of high-performance fiber reinforced composites to reinforce concrete columns can effectively improve the bearing capacity and ductility of concrete columns. In this paper, carbon fiber and aramid fiber were used to reinforce concrete columns respectively. The mechanical properties of high performance fiber reinforced concrete columns were studied. The change of bearing capacity and the relationship between stress and strain were analyzed comprehensively. Experiments show that the fiber reinforced composite material has excellent restraining performance on concrete columns, and the carrying capacity of the reinforced concrete columns has been greatly improved.
