Problems solved by technology

It overcomes the disadvantages of the existing integral abutment-steel pile joint structure, such as large longitudinal rigidity, poor deformation capacity, and easy damage to the pile foundation, and fully utilizes the advantages of rubber plate deformation and good energy dissipation performance to meet the requirements of the longitudinal bridge direction. The demand for horizontal displacement avoids the damage of steel piles under the action of strong earthquakes and the difficulty of repair

Abstract

The invention discloses an improved integral abutment H-shaped steel pile joint anti-seismic structure adhered with rubber plates. The structure comprises an abutment and an H-shaped steel pile, the upper portion of the H-shaped steel pile is embedded into the abutment along the length of the abutment, and the rubber plates are arranged between the H-shaped steel pile embedded into the abutment and the abutment. The abutment is a concrete bridge abutment formed by concrete poured on the peripheries of the rubber plates. And the rubber plates are adhered to the peripheries of webs and flange plates of the H-shaped steel piles embedded into the abutment. The depth of the H-shaped steel pile embedded into the concrete bridge abutment is determined according to sufficient anchoring provided for the H-shaped steel pile. The node anti-seismic structure allows the steel piles and the abutment to relatively rotate to a certain degree, and the allowable longitudinal horizontal displacement of the top structure is increased. According to the node anti-seismic structure, the vertical bearing capacity can be guaranteed, meanwhile, the lateral rigidity is reduced, the structural ductility is improved, the longitudinal-bridge-direction horizontal displacement of the bridge body can be well absorbed, and the anti-seismic property and the energy consumption property of the node are improved.

Description

technical field [0001] The invention relates to the field of optimized design of the anti-seismic performance of integral abutment bridges, in particular to the improvement of anti-seismic and post-earthquake repair performance of an integral abutment-H-shaped steel pile node. Background technique [0002] In the traditional bridge structure, the support and expansion joints at the abutment are the weak points in the bridge. Under the action of the external environment and when an earthquake occurs, they are prone to damage or failure, which affects the normal use of the bridge and increases maintenance costs. However, since the expansion device and support at the abutment of the integral bridge are cancelled, the girder end is directly poured into one body with the abutment, and the deformation of the main girder is mainly adapted to the deformation of the abutment, foundation and soil; the upper part is relieved during the earthquake The displacement earthquake damage of t...
