长细比对BFRP网格ECC复合约束方形RC柱轴压性能影响研究
Effect of length ratio on the axial pressure performance of BFRP grid ECC composite constraint square RC column
摘要
Abstract
The slenderness ratio is an important parameter affecting the axial compression performance of reinforced concrete(RC)columns.Through experimental research,this study investigated the mecha-nisms by which basalt fiber reinforced polymer(BFRP)grids and engineered cementitious composite(ECC)reinforcement measures influenced the load-bearing capacity,ductility,and failure modes of RC columns under different slenderness ratios.Additionally,the effect of BFRP grid-reinforced composite confinement on the axial compression performance of square reinforced concrete columns was explored.The experimental design included seven specimens,comprising an unreinforced control group and several reinforced groups with varying slenderness ratios.The test results indicated that the load-bearing capacity and ductility of the reinforced RC columns were significantly improved,and the bonding performance at the interface between the reinforcement layer and concrete was satisfactory.Experimental data and load-strain curves showed that the load-bearing capacity and ductility of the reinforced columns outperformed those of the unreinforced columns.Although an increase in slenderness ratio led to a slight decrease in the ultimate load-bearing capacity of the reinforced columns,the impact was relatively small,demon-strating that the BFRP grid/ECC composite reinforcement method exhibited good adaptability for columns with different slenderness ratios.关键词
