Abstract: Because of higher—order vibration modes， there are a lot of problems with in high．rise steel structuraI pushover analysis．Pushover analysis method is adopted with the aid of the SAP2000 software to analvze the multilayer and high—rise steel structures in small earthquakes and rare earthquakes． In the analysis various lateral loadin patterns are considered，and the corresponding results，including the nonlinear top．story displacement， story displacement and the distribution of story drifts， are obtained．In order to find a more reas0nable loading partem of high-rise steel structural performance，the seismic performance of structures is assessed．

Key words: pushover analysis；loading pattern；high．rise steel stru cture：seismic performance
