Abstract
This study investigates experimentally flexural behavior and CFB(Carbon Fiber Bar) reinforcing effects of timber sleeper in traditional storied tower house. As a test result, standard sleepers without CFB(Carbon Fiber Bar) reinforcement show flexural cracks at the bottom member at the beginning of loading stage and leads to fracture. However, reinforced specimens with CFB show initial shrinkage at the upper part of specimen by compression, instead of flexural cracks at the bottom, and finally show compressive failure or fracture after failure of CFB and it proves that reinforcing effects by CFB are exerted from early loading. Reinforced specimens showed higher strength in yield strength by 6%~38%, and ultimate strength by 8%~17%, than those of standard specimens. Reinforced specimen is considered that specimen with flexural reinforcement using CFB can expect flexural deflection control effect. Reinforced specimen shows higher ductile coefficient increase of average 141% compared than standard specimens and it proves that higher structural ductile behavior can be expected in reinforced specimens.
