Although slender steel braces are widely used, they buckle prematurely in compression load, and several damages will occur by the deformation. Therefore, the authors have been researching and developing bracing materials in which lightweight, high-strength CFRP materials are anchored to standard pipe-type turnbuckle bodies. Previous studies showed that the material can be easily joined to existing turnbuckle-type braces and can significantly reduce out-of-plane deformation during compressive deformation. This paper shows the impact loading method and conducts to confirm the structural performance under impact loads.
