| Abstract: | Non-linear dynamic time history （NDTH） analyses were carried out on three steel moment resisting frames （SMRFs） with 3-, 6-, and 10-stories by using an ensemble of 15 far-fault earthquake ground motion records, which will help examine the influence of the ground characteristics and structural characteristics on the laws of story distribution of hysteretic energy. The results show that the peak ground acceleration （PGA） has a significant influence on the laws of story distribution of hysteretic energy, but the frequency content, strong mo tion duration and structural characteristics have a minor influence on the laws of story distribution of hysteretic energy. |
