| Abstract: | This paper presents a method of mode decomposition, which equivalently substitutes multi-degree-of-freedom with single-degree-of-freedom about the hysteretic energy and seismic input energy. Through the calculation .and comparison with the multi-degree-of-freedom system and its simplified system, a more satisfactory result is clearly gotten. This work provides a convenient approach for calculating the structure's energy, and also provides a useful and practical method of energy for investigating the damage of structure. |
