“…Double composite action in truss bridges typically has a concrete lower flange between bottom chords in negative moment regions. For example the Nantenbach bridge has double composite steel trusses with a concrete slab and a concrete bottom flange, with a main span of 208 m and side spans of 83.2 m [1]. In composite truss bridges with box-section lower chords, filling the inner spaces of bottom chords with concrete makes the bridge a double composite structure.…”

“…There have been many attempts to increase the economy of long span bridges, including double composite action [1][2][3], hybrid sections [4], truss beams [5] and corrugated steel webs [6]. For steel and concrete continuous composite girders, cracking of the slab in tension increases deflections resulting in reduction of the continuity effect.…”

“…이러한 문제점을 극복하기 위해 본 연구에서는 강재박스 단면의 효율을 최적화하고자 개구단면을 적용하고, 지점부 상부플랜지는 일부구간을 폐합단면 적용하였다 (AASHTO, 2003(AASHTO, , 2004. 또한, 거더 운반 시 높이의 제한 기준을 최소화하 고자 연속지점부 하부플랜지에 고강도 콘크리트를 타설하 여 이중합성을 통한 단면효율 최적화로 지점부 형고를 최소 화하였다 (Saul, 1996). 이를 바탕으로 대상 구조물의 유한요 소해석과 실물시험체의 정적재하실험을 수행하여 구조적 성능을 비교 검증하였다.…”
