An economical comparison of reinforced concrete building resisting frame and dual structures at different performance levels

Keywords: Performance Based Design, Reinforced Concrete Building Stock, Seismicity, Risk-Cost RelationshipsIn this study, reinforced concrete structures will be considered. The aim is to determine whether the economic losses will be disregarded or not when a framed or a shear wall framed structure is designed for predetermined level of seismic performance.To that end, in the first phase, 3, 5 and 8-storey framed and shear wall ? framed 12 structures and their LS (Life Safety) performance levels will be designed for earthquake hazards of 10% and 2% within 50 years. Thereafter, cost analysis of these structures will be determined.As a result, whether framed or shear wall ? framed structures, designed under different performance levels and different earthquake hazards, are economical will come to light. The likely cost of this result for the building stock of the whole country will be discussed.
