| Abstract: | The non-elastic dynamic method is used in the seismic response analysis of structure with varied controlling parameters subjected to differential near-field ground motions. IDARC was employed to establish the simplified analysis model of multi-ribbed energy-dissipated composite wall structure. Under the same conditions, the hysteretic curve of typical layer and coefficient of energy distribution of multi-ribbed energy-dissipated composite wall structure and frame shear-wall structure are compared in the near-field ground motions. The results show that the structure has a good performance of energy dissipation and vibration reduction for near-field ground motions and it is a new ideal aseismic structure system. |
