Experimental Study on Axial Compression Performance of Concrete Short Columns Confined by Carbon Fiber Cloth
Carbon fiber fabric was utilized to reinforce six groups of short concrete columns through circumferential wrapping,investigating the effect of carbon fiber fabric reinforcement on the axial compressive ultimate bearing capacity of the columns.The study analyzed the failure modes and load-strain relationships of the columns reinforced with carbon fiber fabric.Through comparative analysis of test results from each group of specimens,the impact of carbon fiber fabric quantity and arrangement on axial compressive bearing capacity was examined.Experimental findings revealed that as the wrapping spacing decreased,the axial compression of concrete cylinders increased progressively.Under equal layer conditions,larger reinforcement areas resulted in greater constraint on concrete compressive strength and deformation capacity,thereby exhibiting a more significant strengthening effect on concrete.Consequently,during the reinforcement process,CFRP fabric can be employed to augment the axial compression performance of concrete columns.
