Generally, earthquakes recorded within the near-fault characteristic are qualitatively quite different from the usual far-fault earthquake. Because of the unique characteristics of near-fault earthquake, many researchers have developed several performance-based seismic design in order to quantify the damage potential caused by near-fault earthquake. Based on the Taiwan seismic design code and the past research conducted by Okano and Miyamoto [7], this study proposes the modified equivalent linearization method (MELM) of a SDOF system for a low-rise and mid-rise reinforced concrete (RC) building structure subjected to near-fault earthquake. Actually for high-rise building, the engineer needs to do the dynamic analysis. However, for low-rise and mid-rise building in Taiwan actually is not necessary doing the dynamic analysis. Therefore, the purpose of this study is to propose the equation which can help the engineer to estimate the maximum deformation of the building subjected to earthquake so that they do not need to do the dynamic analysis. In addition, for a building structure designed based on the code-suggested static design procedure cannot be used to investigate the damage state of a specified building under the earthquake. Therefore, the constant-damage ductility demand spectrum (CDDDS) for a reinforced concrete (RC) building that corresponds to a specified reliability is developed in this study based on the study conducted by Park and Ang [1].
