abstract
Seismic fragility reflects the ability of a structure to withstand future seismic demands. In order to obtain an accurate assessment of the seismic fragility, it is critical to incorporate information about the current structural properties, which reflects possible aging and deterioration. This paper describes a probabilistic framework to identify the actual conditions of an existing bridge using nondestructive testing (NDT) and to estimate the structure reliability. The proposed probabilistic framework combines global and local damage detection methods. Measurement and modeling errors are considered in the application of the damage detection methods. Then the information obtained from the damage detection is used in newly developed probabilistic capacity and seismic demand models to estimate the seismic fragility of the bridge. Lastly, the proposed probabilistic framework is applied to a reinforced concrete bridge with one single-column bent. 2011 Taylor & Francis Group, London.
