通过对不同加固方式下的钢筋混凝土短柱轴压性能试验,研究了混杂纤维约束混凝土柱的破坏形态及荷载与钢筋、混凝土之间的应变曲线关系,以承载力和延性为指标对比分析了不同混杂方式、混杂体积比的混杂纤维约束混凝土柱的受力性能.试验结果表明:混杂纤维的约束作用可以有效提高柱的承载能力,并使其延性得到显著改善;对于其混杂越均匀和二级拉伸破坏的试件,表现出更好的混杂效果,体现出混杂纤维的优越性.

The axial compressive tests of short steel reinforced concrete columns under different reinforced methods were conducted. Researches on the failure models of hybrid fiber sheets constrained concrete columns and the load-strain curve relationship of steels and concrete were proposed. A comparison on load capacity and ductility was analysed for the mechanical behavior of hybrid fiber sheets constrained concrete columns under different hybrid reinforcing styles besides volumn ratios of hybrid retrofitted amounts. Test results showed that the constraint interaction of hybrid fiber sheets could effectively promote the load capacity of columns and absolutly increase the ductility; when it comes to the specimens more equally strenghened and subjected to 2nd level tensile failure, it turns out a better hybrid effect which indicated the superiority of the hybrid fiber sheets.
