This study proposes an enhanced single-degree-of-freedom (SDOF) system for a two-way all-fixed reinforced concrete (RC) slab. Thus, this study aims to improve the performance of the conventional SDOF system to the level of finite element (FE) analysis. The conventional SDOF system makes incorrect prediction about structural dynamic deflections when a damage occurs during SDOF analysis, because a resistance of the conventional SDOF system cannot reflect stiffness and strength degradation due to damages. In other words, the conventional SDOF model utilizes the inelastic model regardless of its damage occurrence, as the hysterical model. Therefore, it is essential to enhance the SDOF system to minimize the errors. To this end, this study newly utilizes a Modified Plastic-Damage Hysteretic Model (MPDHM) as a resistance function of the SDOF system. Since the MPDHM can reflect stiffness and strength degradation due to damages, the enhanced SDOF system can conduct more reliable predictions than the conventional SDOF system. In order to apply the MPDHM in the SDOF system, its parameter estimation should be preferentially performed based on a number of reference data. For this reason, a series of FE analyses are carried out utilizing commercial S/W (i.e., AUTODYN). The performance of the enhanced SDOF system is numerically validated about a two-way all-fixed RC slab under the different stand-off distances with an identical explosive weight.
