In the 1999 Chi-Chi and 1022 earthquakes, many historic buildings were seriously damaged and the earthquake safety of historic buildings caused attention by the conservator and researcher. 　　The information of earthquake response is the fundamental for the study of earthquake resistant improvement of historic buildings. However, so far in Taiwan there is no historic building which is equipped with strong motion seismometer, and the earthquake response data related to the historic building is not provided. 　　In this thesis, three different types of historic building are selected and analyzed for the purpose of studying the installation of strong motion seismometer. The three buildings are (1) the main hall of Confucian temple, Tainan (Da-Cheng Hall), (2) Li-Shieng building of Cheng-Kung University, (3) the auditorium of Shin-Chung elementary school, Nan-tou. These three buildings are modeled by finite element method and analyzed with computer package program SAP2000. The input ground motion is recorded in the 1022 or Chi-Chi earthquake. The obtained dynamic modes of building in elasticity state and the acceleration response corresponding to the input ground motion are used to plan the arrangement of installation of strong motion seismometer. Based upon these analyses, 36 channels in Da-Cheng Hall, 23 channels in Li-Shieng building and 25 channels in the auditorium of Shin-Chung elementary school are suggested in this thesis. 　　In addition, according to comparison of real earthquake damage and the result of stress analysis at the auditorium of Shin-Chung elementary school, it is found that the occurred place and the pattern of cracks are caused by tensile stress. Furthermore, in this study three methods for strengthening the spacious masonry historic building are provided.
