Application of Energy Dissipation Technology in Structural Seismic Design
In order to explore the seismic isolation performance of viscous dampers in construction engineering,the structural model was established based on the finite element analysis software YJK,and the elastic and elastic-plastic time history analysis of the structure was carried out respectively.The calculation results show that the bottom shear ratio calculated by time history analysis is more than 80%,which meets the minimum structural safety requirements.Under the action of 8-degree fortification earthquake,the interlayer displacement angle of the energy dissipation structure with dampers is basically the same as that of the original structure with x-direction 6% additional damping ratio and y-direction 6% additional damping ratio.The average value of the additional damping ratio in the x,y directions of the structure is 6.05% and 7.31%,respectively.The research shows that the viscous damper is helpful to improve the seismic isolation performance of the structure.
