Steel truss-UHPC composite beam bridge hogging moment area structure and construction method
The invention discloses a steel truss-UHPC composite beam bridge hogging moment area structure and a construction method, and relates to the technical field of bridge structures. The steel truss-UHPCcomposite beam bridge hogging moment area structure comprises a steel truss beam and a UHPC bridge deck slab; the steel truss beam comprises two main trusses which are transversely arranged in a spaced mode and connected, each main truss comprises a lower chord member and an upper chord member, and the lower chord members are filled with UHPC. The UHPC bridge deck slab is connected with the uppersurfaces of the two upper chord members; a vertical web member is arranged between an upper chord member and a lower chord member; pressed web members and pulled web members are symmetrically and alternately arranged on the two sides of the vertical web members in sequence, and the lower chord members and the upper chord members are connected with integral node plates at nodes. The technical problems that the lower chord members of an existing steel truss beam is prone to pressure instability, the bridge deck slab is prone to tension cracking, and a joint is prone to fatigue damage can be solved.
本发明公开了一种钢桁‑UHPC组合梁桥负弯矩区结构及施工方法，涉及桥梁结构技术领域，该包括：钢桁梁和UHPC桥面板；所述钢桁梁包括横向间隔设置且连接的两个主桁架，每个所述主桁架均包括下弦杆和上弦杆，所述下弦杆内部填充有UHPC；UHPC桥面板与两个上弦杆的上表面连接；所述上弦杆和所述下弦杆之间设有竖腹杆，所述竖腹杆两侧依次对称交替设有受压腹杆和受拉腹杆，所述下弦杆和上弦杆在节点处均连接有整体式节点板。本发明能解决现有钢桁梁的下弦杆易受压失稳，桥面板易受拉开裂，节点易疲劳破坏的技术问题。
