Steel-concrete combined section
The invention is applied to the field of bridges, and particularly relates to a steel-concrete combined section, the steel-concrete combined section is used for being arranged between a concrete transition section and a steel beam transition section, the steel-concrete combined section comprises a concrete cast-in-place section and a steel beam connecting section, and the concrete cast-in-place section is used for being connected with the concrete transition section; one end of the steel beam connecting section is connected with the steel beam transition section, the other end of the steel beam connecting section is connected with the concrete cast-in-place section, the connecting face of the steel beam connecting section and the concrete cast-in-place section is of a step-shaped structure in the main pressure stress direction of a main beam, and a pressure-bearing steel plate is arranged on the step-shaped structure. The steel-concrete combined section with the step-shaped combined surface can effectively improve sudden change of bending rigidity and shearing rigidity of the main beams on the two sides of the combined surface, and stress concentration is effectively improved.
本发明用于桥梁领域，特别是涉及一种钢混结合段，所述钢混结合段用于设在混凝土过渡段和钢梁过渡段之间，所述钢混结合段包括混凝土现浇段和钢梁连接段，所述混凝土现浇段用于连接所述混凝土过渡段；所述钢梁连接段的一端连接所述钢梁过渡段，所述钢梁连接段的另一端连接所述混凝土现浇段，沿着主梁的主压应力方向，所述钢梁连接段与所述混凝土现浇段的连接面设为台阶型结构，所述台阶型结构上设有承压钢板。结合面呈台阶形的钢混结合段，能够有效改善结合面两侧的主梁抗弯刚度和抗剪刚度的突变，有效改善应力集中。
