전단 및 휨파괴형 부재가 혼합된 저층 철근콘크리트 건물의 간이 내진성능 평가법 제안

다국어 초록 (Multilingual Abstract)

The 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 immediately. In the current methods, however, the seismic capacities of RC (reinforced concrete) buildings controlled by both shear and flexure have not been fully discussed. These are mainly focused on the strength capacity to withstand earthquake motions without the demand for ductility. This study proposes a new rapid-screening method for more reasonably evaluating the seismic capacities of low-rise RC buildings controlled by both shear and flexure. The proposed method 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. By using the damage estimate method presented in this study, the building performance level associated with a specific level of earthquake demand of low-rise RC buildings that consist of lateral-load resisting members controlled by both shear and flexure can be evaluated. The seismic rehabilitation criteria in terms of expected building performance levels can also be established effectively. The proposed method is verified using observed real damage data of low-rise RC buildings caused by past earthquakes, and applied to existing RC buildings in Korea. 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.
