내부충전 합성 PHC(ICP) 말뚝의 수평저항성능 평가

PHC pile and steel pipe pile have been used in case that high vertical and horizontal loads are applied, respectively. However, steel pipe pile is very expensive because of rising in prices of raw materials. This study was performed to analyze the horizontal performance of PHC Pile reinforced with stirrup, main rebar and infilled concrete, Infilled Composite PHC (ICP) pile. ICP pile can resist horizontal loads on demand by reinforcing stirrups, main rebars and infilling concrete in PHC pile. The bending and shear tests according to KS F 4306 showed that PHC Pile reinforced with stirrups, main rebars and infilled concrete improved in horizontal performance compared to general PHC Pile.
