Current rapid-screening methods, such as the Screening Phase of FEMA 310 and the First Level Procedure in Japanese Standard, have been developed to evaluate seismic capacities of a large number of existing buildings in a short time, and these methods are used first to screen out safe buildings. More detailed methods, such as the Evaluation Phase and the Detailed Evaluation Phase in FEMA 310, the Second Level and the Third Level Procedures in Japanese Standard, are applied subsequently to those buildings only which were not found to be satisfactory by the rapid-screening methods. Therefore, if the rapid-screening methods can screen out safe existing buildings reasonably, these methods will be useful strategy including economical aspects. In the current methods, however, the seismic capacities of RC buildings comprised of shear and flexural failure systems have not been fully discussed. These are mainly focused on the strength capacity to withstand earthquake motions without demand for ductility. This study proposes a rapid-screening method for more reasonably evaluating the seismic capacities of low-rise RC buildings. The method proposed in this study is based on relationships between required strengths of each failure system for ductility factors and damage degrees of overall system derived from the view-point of ductility factors. The proposed method is verified using observed real damage data of low-rise RC buildings caused by past earthquakes. Results indicate that the methodology proposed in this study compares well with real damages and is a useful strategy for rapidly identifying low-rise RC buildings having high potential seismic risk.
