The in-service period of residential houses are too short compared with the return period of earthquakes. Therefore, it is necessary to consider aged deterioration when we measure the effectiveness of seismic retrofit or maintenance against plate boundary earthquakes such as the Nankai earthquake or inland earthquake to occur in several decades. This paper presents a method for predicting earthquake damage probability of wood houses considering aged deterioration affected by biodeterioration and maintenance status. To demonstrate the validity of the proposed method, the damage probability for scenario earthquakes in the Nankai earthquake or inland earthquakes by assuming the oceurrence 25 years later and we discuss how to prepare for these earthquakes.
