Energy-Dissipation Analysis and Design of a Kindergarten Building in High Seismic Intensity Region
The construction details and working principle of viscous damper is introduced.Taking a kindergarten located in an 8-degree seismic fortification area as an example,five natural earthquake waves and two artificial earthquake waves are selected by using the Midas Gen finite element analysis software to analyze the dynamic response of the structure under frequent earthquake and rare earthquake,and the energy consumption of the viscous damper under the three-level earthquakes is given.The results indicate that with the addition of viscous damper,the main structure has good seismic performance and can achieve the"three-level"of seismic fortification goals.Under rare earthquakes,the overall plasticity of the structure is relatively low,and the damage yield mechanism is reasonable.Viscous damper exhibit good energy dissipation characteristics under earthquake action,providing a lower additional damping ratio under rare earthquakes than under frequent earthquakes,and the dispersion of additional damping ratios for multiple sets of seismic waves is also lower.This work can provide reference for similar projects.
