Steel-concrete combined section for large-span double-side box hybrid beam cable-stayed bridge
The invention discloses a steel-concrete combination section for a large-span double-side box hybrid beam cable-stayed bridge. The steel-concrete combination section comprises a steel beam transition section, a combination part and a concrete beam transition section. The steel beam transition section is a section where the main span steel beam extends into the steel-concrete combination section, a plurality of variable cross-section reinforcing stiffening ribs are arranged on a top plate, a bottom plate and a web plate of the steel beam transition section, and the front ends of the variable cross-section reinforcing stiffening ribs are connected with longitudinal stiffening ribs on the top plate, the bottom plate and the web plate of the main span steel beam. The rear ends of the variable cross-section reinforced stiffening ribs are connected with the bearing plate; the joint part is a combined section segment formed by the steel grating chamber and the concrete; the concrete beam transition section is a section, extending into the steel-concrete combination section, of the side span concrete beam; the steel-concrete combined section is simple in structure and reasonable in design, and has the advantages of being high in construction speed, convenient in concrete pouring, high in construction quality and clear in force transmission.
本发明公开一种用于大跨径双边箱混合梁斜拉桥的钢‑混凝土结合段，包括钢梁过渡段、结合部和混凝土梁过渡段；所述钢梁过渡段为所述主跨钢梁伸入至钢‑混凝土结合段内的节段，并在所述钢梁过渡段的顶板、底板和腹板上设置有若干变截面加强加劲肋，所述变截面加强加劲肋的前端与所述主跨钢梁的顶板、底板、和腹板上的纵向加劲肋连接，所述变截面加强加劲肋的后端与承压板连接；所述结合部为钢格室与所述混凝土共同形成的组合截面节段；所述混凝土梁过渡段为所述边跨混凝土梁伸入至钢‑混凝土结合段内的节段；本钢‑混凝土结合段构造简单、设计合理，具有施工速度快，混凝土浇筑方便、施工质量高，传力明确的优点。
