摘　　要：本文提出通过在RC方柱体外缠绕绿色纤维用以约束RC方柱这一新型加固方法,并对比不同缠绕方式、不同缠绕间距的情况下,对RC方柱力学性能的提升情况.试验结果表明,在RC方柱体外缠绕绿色纤维可以有效地提高构件的抗压承载力,通过对比相同缠绕间距下对RC方柱抗压强度的提升情况,采用螺旋缠绕绿色纤维效果更加理想,且缠绕间距越小,提升效果愈加明显.It is a new structural strengthening method to wrap green fiber on the surface of RC square column to restrain RC square column.The recycled steel fiber is mainly from the tire bead of waste automobile.The steel fiber in the tire bead is extracted by factory processing.The recycled steel fiber is from waste tire,which has high strength and stiffness and low price,Green environmental protection,in line with the main melody of today's society and research and development,so recycled steel fiber belongs to green fiber material.This paper proposes a new reinforcement method of binding RC square column by winding green fiber outside the RC square column,and compares the results under different winding methods and different winding spacing,For the improvement of mechanical properties of RC square columns,the test results show that the compression bearing capacity of RC square columns can be effectively improved by winding green fiber outside the RC square columns.By comparing the improvement of compression strength of RC square columns under the same winding spacing,the effect of spiral winding green fiber is more ideal,and with the smaller winding spacing,the improvement effect is more obvious.
