摘要: The feasibility study on carbon fibre reinforced polymer (CFRP) fabrics in axial strengthening of hollow square sections (HSS) was investigated this paper. CFRP used as strips form with other parameters such the number layers and spacing strips. Experimental results revealed that external bonding normal modulus significantly enhanced load carrying capacity stiffness also reduced shortening columns by providing confinement against elastic deformation. increase thickness effectively delayed local buckling above members led to inward rather than outward one. Finally, three-dimensional nonlinear finite element modeling strengthened sectionswas created using ANSYS 12.0 validate numerical failure modes deformation behaviour fairly agreed experimental results.
