Rigid frame system structure of cable-stayed bridge
The invention belongs to the technical field of a cable-stayed bridge and particularly relates to a cable-stayed bridge rigid frame system structure. The structure comprises a tower beam combination structure and a stiffening structure, wherein the tower beam combination structure comprises a steel main beam penetrating through a tower body of a bridge tower, first shear nails arranged at intervals are welded to a web of the steel main beam, the stiffening structure comprises a vertical stiffening steel plate arranged adjacent to an outer side of the bridge tower body, and second shear nails arranged at intervals are welded to the inner side of the vertical stiffening steel plate. The rigid frame system structure is advantaged in that the rigid frame system structure is a supplement to anexisting rigid frame system structure of the cable-stayed bridge, the excellent tensile property of steel and the excellent compression property of concrete can be fully utilized, the local stress property of the steel main beam is improved, the combination of the steel main beam and the concrete bridge tower can be guaranteed, stress is clear, and construction is convenient and fast.
本发明属于斜拉桥技术领域，具体涉及一种斜拉桥刚构体系构造，包括塔梁结合构造和加劲构造，所述的塔梁结合构造包括穿过桥塔塔身的钢主梁，所述钢主梁的腹板上焊接有间隔布置的第一剪力钉；所述的加劲构造包括紧邻桥塔塔身外侧布置的竖向加劲钢板，所述竖向加劲钢板的内侧焊接有间隔布置的第二剪力钉；本发明提供的该斜拉桥刚构体系构造是对现有斜拉桥刚构体系构造的一种补充，结合计算分析，本发明提供的刚构体系构造能够充分利用钢材优异的受拉性能及混凝土优异的受压性能，改善钢主梁局部受力性能，且钢主梁与混凝土桥塔的结合能够得到保证，受力清晰，施工便捷。
