Structural Performance Deterioration Index of Reinforced Concrete Cultural Property Buildings

Abstract

Most RC buildings with cultural value constructed over 50 years ago have structural safety problems. To continue maintenance and conservation of these buildings, evaluation of safety performance is required. In this study, on-site surveys of existing RC cultural property buildings were conducted to classify the degree of deterioration of their structural members. Further, a comparative investigation of methods of applying reduction factors of structural performance according to the degree of deterioration that were proposed in previous studies to actual RC cultural properties was carried out. Finally, based on the findings of this study, a procedure for investigating the degree of deterioration of RC cultural heritage buildings and reflecting it in seismic performance evaluation is proposed.
