Title: Material strength safety factors for the seismic safety assessment of existing RC buildings
Issue Date: 2016
Abstract: New material safety factors (CFmat) are proposed to characterize material strength in existing buildings.These safety factors are developed in order to be compatible with seismic safety assessment proceduresdefined by current standards such as Eurocode 8 Part 3. The general theory behind the development ofthe CFmat safety factors considers the uncertainty associated to the number of surveyed structuralelements and the inherent variability of the material strength under analysis. The CFmat safety factorsare developed using a finite population approach where the material properties in a building are discretizedby considering one value per element. The proposed theory is used to define specific CFmat valuesand survey plans for the concrete compressive strength and for the reinforcing steel yield strength.
