Analysis of Local Failure Machanism of Fiber Reinforced Concrete by Impact of High-Velocity Projectile
초록
In this study, flexural strength by fiber reinforced for steel fiber and reinforced polyamide fiber concrete, and concrete fracture properties by improvement of flexural toughness and high-velocity projectile impact were evaluated. As a result, it was confirmed that flexural strength are improved by distribution of stress and suppress of cracks, and the back desquamation of concrete by high-velocity projectile impact is suppressed. In addition, It was observed that the spalling of rear is caused when tension stress is caused as shock wave by high-velocity projectile impact was transferred to the rear and tension stress is suppressed by fiber reinforcement.
