Based on SAP2000 software,four models(corrosion rate 0％,5％,10％,15％)were established for a seven story reinforced concrete frame structure of an office building.The equal acceler-ation displacement loading mode and modal displacement loading mode were adopted.Through the Pushover analysis method based on capacity spectrum,the seismic performance of this frame structure under different corrosion rates was obtained.The changes in the base shear vertex displacement and in-ter story displacement angle of the structure under increasing corrosion rate were analysed,and corre-sponding conclusions were drawn.The aim is to provide theoretical basis for related engineering in the design,seismic performance evaluation,and reinforcement and maintenance of frame structures.
