Steel-concrete composite beam and cable-stayed bridge
The invention discloses a steel-concrete composite beam and a cable-stayed bridge. The composite beam comprises a main-span truss girder and a side-span truss girder, the main-span truss girder comprises a main-span concrete bridge deck, two main-span steel trusses and a main-span steel lower parallel connection, the two main-span steel trusses are symmetrically arranged in the transverse bridge direction, the main-span concrete bridge deck is connected with the tops of the two main-span steel trusses, the main-span concrete bridge deck is connected with the tops of the two main-span steel trusses, and the main-span steel lower parallel connection is connected with the bottoms of the two main-span steel trusses; and at least one end of the two opposite ends of the main-span truss girder in the longitudinal bridge direction is provided with the side-span truss girder, the side-span truss girder comprises a side span concrete bridge deck, two side span steel trusses and a side span concrete lower parallel connection, the two side span steel trusses are symmetrically arranged in the transverse bridge direction, the side span concrete bridge deck is connected with the tops of the side span steel trusses, and the side span concrete lower parallel connection is connected with the bottom of the side span steel trusses. According to the steel-concrete composite beam and the cable-stayed bridge, the spanning capacity of the cable-stayed bridge is guaranteed, and meanwhile the engineering economy is improved.
本申请实施例提供了一种钢混组合梁及斜拉桥，包括主跨桁架梁及边跨桁架梁，主跨桁架梁包括主跨混凝土桥面板、两片主跨钢桁架和主跨钢下平联，两片主跨钢桁架沿横桥向对称设置，主跨混凝土桥面板与两片主跨钢桁架的顶部连接，主跨钢下平联与两片主跨钢桁架的底部连接；主跨桁架梁沿纵桥向的相对两端的至少一端设置边跨桁架梁，边跨桁架梁包括边跨混凝土桥面板、两片边跨钢桁架和边跨混凝土下平联，两片边跨钢桁架沿横桥向对称设置，边跨混凝土桥面板与边跨钢桁架的顶部连接，边跨混凝土下平联与边跨钢桁架的底部连接。本申请实施例的钢混组合梁及斜拉桥在保证斜拉桥跨越能力的同时，提高了工程经济性。
