Analysis Of Seismic Performance Of Shear Wall Structure With Metal Dampers

In recent decades,high-rise buildings in our country have developed rapidly,with endless structural forms and diversification High-rise Shear Wall structure is a very common building structure at this stage.It has the characteristics of applicability,safety,durability and economy.With more and more buildings of Shear Wall structure in our country,more and more earthquake disasters may occur in the future,so we need to study the seismic behavior of Shear Wall structure.The common ways to increase the seismic capacity of Shear Wall structure include increasing concrete strength,etc.The metal damper is arranged in the shear wall structure,which can provide additional damping and stiffness to the structure.This paper analyzes and studies the seismic performance of metal dampers added to the shear wall structure.The main work contents are as follows:(1)After analyzing the research methods and achievements of energy dissipation and shock absorption of domestic and foreign shear wall structures and coupling beam dampers,an engineering example of a high-rise shear wall structure with a height of 90 meters was determined and selected.(2)According to the classification of the dampers used in civil engineering structures,based on the analysis and summary of the main characteristics of various types of dampers,the shear steel plate dampers were selected to study the mechanical model and related damping design methods.(3)Finite element software ETABS,examples establish elastoplastic analysis model structure and seismic profiling.Time history analysis of the model is arranged to shear-cut the damper and contrast differences shear wall structure is arranged to shear-cut the original structure of the damper in the interlayer shear layer displacement angle,and damper hysteresis curve.And seismic wave energy map for analysis.
