Updating Material Factors for Assessment of Historic Reinforced Concrete Bridge

Abstract

This paper is focused on the reliability analysis of an existing reinforced concrete bridge from 1908. The load bearing capacity is assessed in accordance with valid standards using updated partial factors and the partial factors for structural design. Load bearing capacities obtained by these methods are critically compared. The application of the updated partial factors leads to 15% higher load bearing capacity than the ordinary partial factor method used for structural design.
