Abstract

A fish-bone type bridge is vulnerable to the torsional behavior due to the single girder system with planar zigzag conformation. The fixed connecting area between the girder and pier is the special weak point because the torsional load creates excessive stress concentration. Therefore, the method to reduce the stress concentration is required. In this study, the reduction efficiency of various reinforcing types to reduce the excessive stress occurring at the connecting area is evaluated by using numerical analyses.

조립식지그재그 형태의 단일거더시스템이 적용되는 경골형 교량은 비틀림에 취약한 구조이다. 특히 거더와 PHC(Pretensioned spun High strength Concrete) 말뚝의 고정 연결부는 비틀림 하중에 의한 과도한 응력이 집중되는 취약부이므로 이를 저감시키기 위한 방안이 요구된다. 본 연구에서는 연결부에 발생하는 과도한 응력을 저감시키기 위한 다양한 보강재 형식의 효율성을 수치해석적으로 평가하였다.
