Crescent　arch　-　continuous　beam　composite　bridge　structures　combine　crescent　arch＇s　novel　modeling　and　advantages　of　a　arch　continuous　beam　bridge　structure,　which　is　first　applied　for　Zhangzhou　Jiulong　River　Bridge.　A　full-bridge　plexiglass　model　test　of　a　crescent　arch　-　continuous　beam　composite　bridge　structure　was　conducted.　Three　structural　tests　were　done,　which　are　a　crescent　arch　-continuous　beam　composite　bridge　structure,　the　vice　suspender　removed　and　the　vice　arch　removed　-　continuous　beam　composite　bridge　structure,　and　the　crescent　arch　and　suspender　removed　continuous　beam　structure.　The　research　on　structural　responses　under　loads　shows　that　mechanical　performance　of　a　crescent　arch　-　continuous　beam　composite　bridge　structure　is　better　than　continuous　beam　structure　and　common　arch　-　beam　composite　bridge　structure.　This　result　is　beneficial　to　promote　the　application　of　a　crescent　arch　-　continuous　composite　bridge　structure.　©,　2015,　Editorial　Office　of　China　Civil　Engineering　Journal.　All　right　reserved.
