1 29ƒ 5A Á œ pp. 519 ~ 529 gj p ª gj p w q {- w x Experimental Analysis of Large Size Concrete-Filled Glass Fiber Reinforced Composite Piles Subjected to the Flexural Compression Á y Lee, Sung WooÁChoi, Sokhwan Abstract Fiber reinforced composite materials have various advantages in mechanical and chemical aspects. Not only high fatigue and chemical resistance, but also high specific strength and stiffness are attained, and therefore, damping characteristics are beneficial to marine piles. Since piles used for marine structures are subjected to compression and bending as well, detailed research is necessary. Current study examine the mechanical behavior under flexural and/or compressive loads using concrete filled fiber reinforced plastic composite piles, which include large size diameter. 25 pile specimens which have various size of diameters and lengths were fabricated using hand lay-up or filament winding method to see the effect of fabrication method. The inner diameters of test specimens ranged from 165Gmm to 600Gmm, and the lengths of test specimens ranged from 1,350 mm to 8,000Gmm. The strengths of the fill-in concrete were 27 and 40GMPa. Fiber volumes used in circumferential and axial directions are varied in order to see the difference. For some tubes, spiral inner grooves were fabricated to reduce shear deformation between concrete and tube. It was observed that the piles made using filament winding method showed higher flexural stiffness than those made using hand lay-up. The flexural stiffness of piles decreases from the early loading stage, and this phenomenon does not disappear even when the inner spiral grooves were introduced. It means that the relative shear deformation between the concrete and tube wasn't able to be removed.
