| Abstract: | This paper presents a study on identifying the hysteretic energy demand and its distribution throughout the story of steel moment resisting frames（SMRFs） subjected to severe earthquakes. A total of 30 far-fault and near-fault earthquake ground motion records were selected in this study. Non-linear dynamic time history（NDTH） analyses were carried out on three SMRFs with 3-, 6-, and 10-stories. Comparative analyses were carried out on the story distribution of hysteretic energy demand and the story drift for SMRFs. By the regression analysis, a simplified formula of hysteretic energy demand distribution throughout the story of SMRFs subjected to severe earthquake ground motions was presented. |
