Method for carrying out seismic resistance on flue gas desulfurization building by adopting damper

Abstract

The invention discloses a method for carrying out seismic resistance on a flue gas desulfurization building by adopting a damper. The method comprises the following steps: constructing a column body;fixing the column body on a foundation base; calculating the height of a seismic resistant reverse edge, and building the seismic resistant reverse edge according to the calculated height; calculatingthe support stiffness of a required damper; providing a damper according to the required support stiffness of the damper; arranging the damper between the column body and the seismic resistant reverse edge, wherein the step of calculating the required support stiffness of the damper comprises the following steps: determining the inherent structure frequency, the interlayer height, the seismic resistant and anti-intensity level and the interlayer displacement angle; calculating the interlayer displacement and the interlayer displacement angle when the damper reaches the positioning displacement and the damping force reaches the maximum damping force; and calculating the support stiffness of the damper based on the displacement limit value and the energy consumption effect formula when theinterlayer displacement reaches the basic intensity. The method can effectively reduce energy caused by earthquakes and wind loads, and is high in seismic resistant capacity and efficiency.

Description

technical field [0001] The invention relates to the technical field of shock absorption of flue gas desulfurization structures, in particular to a method for anti-vibration of flue gas desulfurization structures by using a damper. Background technique [0002] There are many conventional designs for flue gas desulfurization buildings and structures. The traditional method of relying on the damage of the structure itself under a large earthquake (that is, relying on ductility) has been adopted to resist earthquake damage. However, there are problems such as rigid seismic design and insufficient ductility of the structure itself. The traditional design method, which takes "no collapse after a big earthquake" as the main goal of structural seismic design, requires a large number of strict seismic structural measures according to the different seismic levels of the building, which not only greatly increases the consumption of materials, but also increases the difficulty of constr...

[0002] There are many conventional designs in flue gas desulfurization buildings and structures, and the traditional method of relying on the damage of the structure itself under a large earthquake (that is, relying on ductility) to resist earthquake damage has been adopted, but there are problems such as rigid seismic design and insufficient ductility of the structure itself.

The traditional design method, which takes "no collapse after a big earthquake" as the main goal of structural seismic design, requires a large number of strict seismic structural measures according to the different seismic levels of the building, which not only greatly increases the consumption of materials, but also increases the difficulty of construction accordingly, thus greatly increase the cost
