The Comparison Between Seismic Evaluation Methods in Taiwan

This study mainly focuses on the introduction of a database of the compulsory school buildings and comparison between the three seismic evaluation methods?strength-ductility method (the prescribed method), NCREE preliminary evaluation method, and pushover analysis method?in Taiwan. The detailed database provides the detailed data of the school buildings to the engineers and researchers who want to analyze and research the compulsory school buildings. The three seismic evaluation methods will be compared using the detailed data from the database. Based on the in situ pushover experiment result conducted by the National Center for Research on Earthquake Engineering (NCREE) in Hualien County, the strength-ductility method was more conservative than other two methods. The NCREE preliminary evaluation method, developed by NCREE, is based on the ratio of the lateral load capacity and demand of the constructions considering the important factors. Hence, the method is scientific and systematic. Dr. Tu?s model is used in the pushover analysis. The differences and correlations between the three methods will be thoroughly presented in this study.
