FRP Reinforced Short Wood Columns under Axial Compressive Load

Abstract:

This paper presents experimental research on axial structural behaviour of 14 short wood columns externally strengthened with CFRP, BFRP and AFRP fibers. All columns for tests were subjected to axial compressive load. The work carried out has indicated how different types of fiber cloth, strengthened arrangements and fiber layers affect behaviour of the short reinforced wooden columns. Research output shows that carrying capacity, stiffness and ductility of FRP reinforced wood columns is improved, and the increasing relationship between the reinforcement layers and bearing capacity is not linear. The all-bonded reinforcement scheme is better than semi-bonded one, and the semi-bonded one is better than the interval-bonded one. The performance of CFRP and BFRP reinforced columns is applied fully. This study confirms that the FRP reinforcing technique significantly enhances the carrying capacity of short wood columns.
