Abstract
ABSTRACT The limit states design method is replacing the allowable stress design method worldwide, e.g. the design code of ISO and various construction codes of Korea are adopting the reliability based limit state method. This paper proposed LRFD design value which is one of limit states design method for the PHC bored pile used as building foundation. This paper analysed 81 load test results and the bearing design(Meyerhof method & SPT-CPT conversion method), and proposed LRFD value for each design reliability Index 2.33 and 3.0 for PHC bored pile. LRFD value of PHC bored pile represents 0.36～0.44 for Meyerhof method and 0.24～0.31 for SPT-CPT conversion method according to the deign reliability index. Key words: PHC Pile, Bored Pile, Limit States Design Method, LRFD(Load and Resistance factored Design Method), Deign Reliability Index 본 논문은 토지주택연구원의 ‘말뚝기초의 설계법 선진화 및 시공법 다양화 연구’의 일부분을 정리한 내용입니다.1) 토지주택연구원, 수석연구원(주저자: jbpark@lh.or.kr)2) 토지주택연구원, 수석연구원(교신저자: parkyb@lh.or.kr)3) 토지주택연구원, 수석연구원
