Abstract

Based on the study of seismic design of viscous dampers short-leg shear walls structure,it is summarized and improved the installment location and traditional calculation methods.It is put forward the method of distributing damping coefficient according to the direct ratio of damping force and floor shear,and also adopted the idea of accumulation to realize more accurate calculation of additional damping ratio needed in the structure.Combining real cases,and through comparison of designs,the paper has built finite element models and performed time-history analysis for common shear wall structure,short-leg shear wall structure,short-leg shear walls + viscous damper structure.It is proved that viscous dampers performs better in energy consumption,which makes the structure components maintain the safe state of elastic deformation,makes up shortcomings existing in the short-leg shear wall structure,and secures the building is more economical.Additionally,through simulated destruction test on the vibration table,it is further verified the outstanding shock absorption effect of viscous dampers in short-leg shear wall structures.
