STRUCTURAL DURABILITY ASSESSMENT FOR OLD CONCRETE BRIDGE USING TIME VARIABLE RELIABILITY ANALYSIS
Concrete structural durability of old concrete bridge is vital for structure integrity assessment at service state. The influence of the concrete carbonation and the induced rebar corrosions and the resistance force function degradation with time elapsed were studied. The structural resisting force as a function of service was investigated. The time-variant reliability analysis was proposed for structural integrity assessment. The OpenSees reliability analysis module was applied in the analysis. The FORM was used to derive the reliability index in each service time. The evolution of the reliability was obtained. The proposed method was applied in an old concrete bridge time variant reliability analysis.
