Abstract

The steel corrosion is usually displayed in the form of cracking and spalling of the concrete cover due to the expansion of corrosion products. Structural distress due to either loss of bond along the steel/concrete interface resulting from splitting of the concrete cover, or reduction of the cross-sectional area of the reinforcing bars can be caused over time. The time-variant reliability analysis and seismic fragility analysis are combined together to form a continuous fragility curve in load as well as in time. The uncertainties of material deterioration may affect the seismic performance evaluation of bridges. The tornado diagram analysis has been used here due to its simplicity and efficiency to identify sensitivity of uncertain parameters of material properties and section dimensions.
