Experimental Study on Axial Compressive Behavior of Faux Wood Column Reinforced by CFRP Cloth
To improve the mechanical properties of faux wood column under axial compression,carbon fiber reinforced polymer(CFRP)is bonded to their surface for reinforcement.Considering the influence of the number and method of CFRP bonding layers,monotonic axial compression tests were conducted on four groups of faux wood column specimens with simply supported ends to understand their loading process and failure modes.Load-displacement curves and load-strain curves were obtained.The results show that bonding CFRP cloth can effectively constrain the lateral deformation of the faux wood material in the axially compressed columns.Compared with unreinforced faux wood column,it can effectively improve the bearing capacity and ductility of the faux wood column,and the improvement effect becomes more effective as the amount of CFRP cloth bonded increases.The greater the amount of CFRP bonded,the stronger the confining effect on the faux wood material,and the higher the peak stress and ultimate strain of the faux wood column specimens.
