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. Therefore, if the rapid-screening methods can screen out existing safe buildings reasonably, these methods will be useful strategy including economical aspects. In the current methods, however, the seismic capacities of reinforced concrete(RC) buildings controlled by both shear and flexure have not been fully discussed, also these are mainly focused on the strength capacity to withstand earthquake motions without demand for ductility. The purpose of this study is to propose a new rapid-screening method for more reasonably evaluating the seismic capacities of low-rise RC buildings. In this study, the equations of damage judgement and seismic capacity evaluation for quantitatively estimating the seismic performance were developed. In order to investigate a practical applicability of the proposed method, on the other hand, seismic capacities of two RC building examples including a pure frame and a frame with shear walls are evaluated based on the proposed method. |
