Embodiment 1

[0031] Double-column ultra-high rigid frame pier connected by multiple steel members, including pier column 1 and cross-connection member 2 used for connection between pier columns 1, cross-connection member 2 is located between pier columns 1, and cross-connection member 2 passes through The plane formed by the centerline of the connected pier column 1 is X-shaped, so as to convert the bending moment acting on the pier into tensile and compressive axial loads.

[0032] During work, the bending moment acting on the pier column 1, such as the bending moment caused by an earthquake, can be transmitted to the adjacent pier column 1 by the cross-link member 2, and the bending moment can be further converted into tension and compression through the X-shaped structure. In this way, the pier column 1 can give full play to the performance of bearing tension and compression loads, thereby enhancing the seismic performance of the double-column ultra-high rigid frame pier. At the same ti...

Abstract

The invention relates to the technical field of road and bridge construction, in particular to a double-column super-high rigid frame pier connected by multiple heavy steel members. Includes at leasttwo pier columns connected with transverse connecting members between adjacent pier columns; The transverse coupling members are X-shaped and arranged adjacent to each other in a vertical direction ona plane formed by a centerline of an adjacent pier column; The X-shaped transverse member is at least two so as to convert the horizontal transverse load acting on the pier into its axial tensile andcompressive load. Beneficial effect: The transverse load of the pier column is transformed into axial load through the transverse connecting member of the high-strength steel structure, and the bending moment of the pier column is small, so that the characteristics of good compression resistance of the reinforced concrete pier column and the lightweight and high compression strength of the high-strength steel structure can be fully utilized, thereby enhancing the seismic performance of the double-column ultra-high rigid frame pier.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a double-column ultra-high rigid frame pier connected by multiple steel components. Background technique [0002] With the development of my country's transportation construction, especially the construction of bridges in mountainous areas of our country, it is controlled by terrain, landform, and earthquake conditions. During the construction process, it is inevitable to use high-pier long-span bridge structures, which are subject to the live load and stiffness requirements of the bridge. The control of bridge piers needs to have a larger size to ensure their longitudinal and transverse stiffness. In order to reduce the seismic action of high-pier bridges in earthquake zones, the structure must be light in weight and weak in stiffness. How to solve these contradictions while making the The structure is economical and reasonable, which brings great difficulties...
