The　main　bridge　of　a　Huanghe　River　Bridge　carrying　a　section　of　the　Gaoqing-Shanghe　Expressway　is　a　concrete-filled　steel　tubular(CFST)　tied　arch　bridge　with　four　continuous　spans　of　190,　260,　260　and　190　m.　The　arch　is　fixed　with　the　piers　instead　of　the　deck.　The　total　deck　width　reaches　43.　2　m.　The　two　parallel　CFST　truss　arches　are　connected　by　K-bracings　and　Warren-type　bracings,　and　rows　of　studs　are　installed　inside　the　nodes　of　the　tubes　to　improve　the　fatigue　life　of　the　arch.　At　the　arch　springings,　each　hanger　point　contains　two　compacted　steel　wire　hangers(namely　the　short　hangers　No.　1　and　No.　2),　the　remaining　hanger　points　incorporate　one　compacted　steel　wire　hanger.　Three　groups　of　a　total　number　of　24　ties　are　installed　to　balance　the　arch　thrust.　The　deck　System　consists　of　two　main　steel　1　longitudinal　girders,　steel　1　floor　beams　and　steel　I　stringers,　and　all　the　components　are　connected　by　high-strength　bolts.　The　24　cm-thick　precast　C50　concrete　panels　were　jointed　via　pouring　microexpansion　concrete.　The　skewbacks　are　trapezoidal　steel-cladding　concrete　struetures.　The　piers　are　reetangular　hollow　piers　supported　by　bored　piles.　To　balance　the　load　bearing　performance　of　the　structure　and　multiple　factors,　including　construction　safety-　quality*　schedule　and　economy,　the　deck　was　installed　ahead　of　the　arch,　and　the　ties　and　hangers　were　tensioncd　in　batches.　The　structural　strength　and　stability　of　the　main　bridge　as　well　as　the　load　bearing　behaviors　of　the　skewbacks　were　numerically　calculated　and　validated,　using　spatial　link　elements　and　solid　elements　respectively.　©　2025　Wuhan　Bridge　Media　Co.,　Ltd.,　MBEC.　All　rights　reserved.
