Simple and compact type three-dimensional friction pendulum vibration insulation support

Abstract

The invention relates to the field of civil engineering, in particular to a support capable of achieving vibration mitigation and isolation of a building, in particular to a support capable of achieving horizontal vibration mitigation and isolation and vertical vibration mitigation and isolation at the same time, and particularly relates to a simple and compact type three-dimensional friction pendulum vibration isolation support. The simple and compact type three-dimensional friction pendulum vibration isolation support comprising two sets of support plates and spherical crown lining plates which are connected through friction sliding pairs, wherein vertical vibration isolation units are arranged between the two spherical crown lining plates, and horizontal and vertical vibration mitigation and isolation are realized at the same time.

Description

technical field [0001] The invention relates to the field of civil engineering, and relates to a support capable of realizing shock absorption and isolation of buildings, especially a support capable of simultaneously realizing horizontal and vertical shock absorption and isolation, in particular to a compact three-dimensional friction pendulum shock isolation support. Background technique [0002] At present, the seismic isolation bearings realized in engineering applications are mainly used to reduce horizontal vibrations, and those that can simultaneously reduce vertical vibrations are rare in practical applications. In addition, due to the vertical vibration caused by rail traffic, ordinary seismic isolation bearings cannot be isolated, which will affect the comfort of the building, and even the normal use of some buildings. Many designers at home and abroad have also proposed a variety of concepts and structures of three-dimensional isolation bearings, which can reduce ...

Problems solved by technology

However, due to the large size of the structure and the absence of energy-consuming units in the vertical direction, many design schemes currently have high cost and poor practicability, and there are relatively few practical applications.
