Problems solved by technology

During the earthquake, the concrete at the joint between the steel pile head and the abutment is directly contacted and squeezed, and the concrete has low deformation capacity, which is easy to crack and partially crush, which affects the ductility of the structure. Therefore, it is necessary to improve the integral abutment-steel pile joint

Abstract

The invention discloses an integral abutment H-shaped steel pile node anti-seismic structure locally using rubber concrete, which comprises an abutment and an H-shaped steel pile embedded into the abutment along the length of the abutment, and the rubber concrete embedded into the concrete abutment is poured on the periphery of the top of the H-shaped steel pile. And the strength of the rubber concrete is basically consistent with that of concrete forming the abutment. Ordinary concrete can be alternately arranged with the rubber concrete in the length direction of the abutment, or corrugatedsleeves are arranged between the rubber concrete and the side face of the abutment. According to the integral abutment H-shaped steel pile node anti-seismic structure, the rotating capacity of the integral abutment H-shaped steel pile node is improved, the lateral rigidity is reduced, the allowable horizontal displacement of a top structure in the longitudinal direction of a bridge is increased, the ductility and crack resistance of concrete at the integral abutment H-shaped steel pile node are improved, and the anti-seismic property of the node is improved. The use of the rubber concrete is beneficial to solving the problems of environmental protection and resource shortage caused by waste rubber, and the social effect is remarkable.

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 the anti-seismic performance of an integral abutment-H-shaped steel pile joint. 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 the structure avoids th...
