| Abstract: | In this paper, the nonlinear time-history analysis was applied to the 10 storeys, 15 storeys, 20 storeys of the single diagonal centrically braced steel frame structure in order to analyze the hysteretic energy demand distribution along the structural height by using 10 far-fauh earthquake ground motions （EQGM） and 10 nearfault earthquake ground motions. The contrastive analysis was made on the hysteretic energy demand interlaminar distribution under the action of the far-fault and near-fault earthquake ground motions, and the simplified calculation formula of the hysteretic energy demand distribution along the structural height was presented, which can provide technical preparation for the centrically braced steel frames based on the earthquake-resistance design research. |
