Building vibration reduction method and vibration reduction effect evaluation method influenced by rail transit vibration

Abstract

Embodiments of the invention provide a building vibration reduction method and a vibration reduction effect evaluation method influenced by rail transit vibration. The overall vibration reduction method comprises: obtaining the target vibration reduction rate of a newly-built building based on the base vibration amount and the target vibration amount; obtaining a target inherent frequency of the newly-built building based on the target vibration reduction rate; and obtaining the rigidity of the vibration damping pad based on the target inherent frequency, and obtaining the vibration damping building with the target vibration damping function after the vibration damping pad is installed on the building base. According to the overall vibration reduction method and the vibration reduction effect evaluation method for the building affected by rail transit vibration provided by the embodiment of the invention, the target vibration reduction rate is obtained by newly building the base vibration quantity and the target vibration quantity of the building, then the target inherent frequency is obtained, and finally the rigidity of the vibration reduction pad is designed; wherein the vibration reduction pad is used for obtaining a newly-built vibration reduction building with a vibration reduction function; and the vibration reduction effect of the vibration reduction building is evaluated, so that the vibration influence of the rail transit can be effectively avoided for the newly-built building.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of building vibration reduction, and in particular to a method for reducing overall building vibration affected by rail transit vibration, a vibration-damping pad, and a method for evaluating the vibration-damping effect of a vibration-damping building. Background technique [0002] Rail transit is the main artery of urban development. It not only greatly improves the efficiency of urban travel, but also stimulates the vitality of the city's economy and society, and improves the city's comprehensive carrying capacity and urban quality. Therefore, the construction of urban rail transit network is of great significance. [0003] Under the background of the exponential growth of urban rail transit mileage and the continuous densification and expansion of the line network, rail transit lines and existing or newly built residences, hospitals, schools, research institutes, concert halls and ot...
