Problems solved by technology

However, for girder bridges that need to consider earthquake action at the same time, simple sliding bearings often lead to excessive displacement between the structural girder and the sliding device under earthquake action, which in turn leads to beam drop due to excessive relative displacement under earthquake action destroy

Abstract

The invention discloses a composite shear plate damper which comprises a structural connecting plate, a clearance low-friction limiter and a shear plate damper body. The shear plate damper body is formed by fixedly connecting the upper end and the lower end of a shear energy-consumption plate with a sliding bearing plate and a support connecting plate respectively. The clearance low-friction limiter comprises a sliding cover plate, a low-friction material body and a limiting block, the sliding cover plate is fixedly connected with the structural connecting plate, the limiting block is fixedly connected with the sliding bearing plate, the low-friction material body is located between the sliding cover plate and the sliding bearing plate, and a certain clearance is reserved between the sliding cover plate and the limiting block. The composite shear plate damper solves the problems that the shear yield force of the shear plate damper is high, and the temperature stress in the structure cannot be released smoothly; due to the clearance low-friction limiter, according to the structure, under the temperature action, the composite shear plate damper is used as a support and can slide freely, the possibility that higher temperature stress exists in the structure is avoided, and the application range of a traditional shear plate damper in the temperature sensitive structure is broadened.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to a combined shear plate damper for reducing structural temperature stress and earthquake response. Background technique [0002] The shear plate damper is a metal yield energy-dissipating damper. Usually, under the action of a small earthquake or wind vibration, the shear plate is in the elastic range, providing a certain lateral stiffness for the main structure; When activated, the shear plate damper dissipates vibrational energy through shear yield hysteresis. However, for temperature-sensitive structures, the shear plate damper in the structure is in the elastic range under the action of temperature, which limits the deformation of the structure, resulting in a large temperature stress inside the structure. [0003] For structures such as beam bridges that are greatly affected by temperature stress, the commonly used method is to change the one-end support to a sliding support wi...
