Abstract

Abstract

Ten timber columns strengthened with CFRP strips and AFRP bars were tested and effective factors such as shape and layer of CFRP strips,layout of AFRP rods were studied. The ultimate load-bearing capacities of timber columns with CFRP strips are increased by about 7.6%～26.1% over the control specimen,and the ductility performance also has a significant betterment. The ultimate load-bearing capacities of timber columns with AFRP rods have 17.7%～41.5% increases over the control specimen,and after wrapped with CFRP strips,the ductility has an obvious improvement. Based on the experimental research,the strength mode of timber columns strengthened with CFRP strip was proposed,and the effective confined coefficient k1 was linearly regressed. Strengthened timber column with CFRP is a valid method,and it can be used for strengthening of timber structures.
