Abstract: Assessing structural response of super high-rise building under rare earthquake is a critical aspect for structural seismic design. By using nonlinear software with appropriate parameters, stmctural performance and component performance can be precisely observed to work on structural design.  In this paper, provided on the ABAQUS and PERFORM-3D platform, the main analysis procedures and some key parameters are outlined for elasto-palstic time-history analysis. Based on engineering practice, the stmctural performance under rare earthquake is studied and evaluation essentials concluded as well.
