Overview of Building Seismic Mitigation and Isolation
With the promulgation and implementation of the Administrative Regulations on Earthquake Resistance of Construction Projects in China on September 1,2021,the seismic mitigation and isolation technology has been used as a mandatory technical measure in buildings within two zones and eight categories.In this paper,the authors summarize the application of structural vibration reduction and isolation technology commonly used in China at this stage.This paper introduces the product system of seismic absorption and isolation,the working principle and damping effect of seismic absorption and isolation structures,the comparison between the economy of seismic absorption and isolation,and how to meet the normal use requirements of buildings under the action of earthquake fortification.
