An experimental study about structural behavior of CFRP Bar embedded into wood surface

Abstract

Recently there has been an increase in people’s interest in friendly-environment wooden-structure buildings due to changes in the diversified housing environment. Resulting from such increased interest . there is also growth in the amount of consumed and imported woods required for various designs of wooden buildings. However, due to lack of experience in designing such buildings, many problems have arisen, including excessive dependence on traditional wooden architectures. This study conssiders the construction method of inserting a CFRP Bar into the wooden surface. From a comparison of maximum internal force, the experimental specimen group reinforcing the lateral side and the bottom side of wood showed an increased maximum internal force over 50% more than the non-reinforced specimen group, so it is known that if the load reduction rate, ΔPmax is increased, the transformation rate of CFRP Bar is increased. From this result, it is also known that the CFRP Bar properly distributes the external force being exercised from outside, and this proposed construction method is effective.
