Abstract:Combining with performance grades of reinforced concrete structures at home and abroad,and according to the failure characteristics and the demand of seismic performance of core wall structure,this paper divides the seismic performance of reinforced concrete core walls structure into four levels:normal service,temporary service,life safety and collapse prevention.Based on the force,the deformation and the failure characteristics of concrete coupling beam and shear wall,the failure judgment standard and deformation limit values are proposed according to the four seismic performance levels.In summing up the experiment study of core wall seismic performance of this paper and other domestic research data,the story drift angle limitation is obtained corresponding to these four different seismic performance levels.Finally,considering the ideas of performance-based seismic design for high-rise structure,such problems about performance index limit values still need further study about concrete core wall structures.
Keywords:core walls  seismic performance levels  failure modes  performance index
