DEVELOPMENT OF BRIDGE FRAGILITY CURVES

This paper presents preliminary results of an on-going research on bridge fragility curve development focusing on (1) development of empirical fragility curves utilizing bridge damage control obtained from the past earthquakes, particularly the 1994 Northridge earthquake, (2) development of analytical fragility curves, on the basis of dynamic analysis, (3) the issues of hypothesis testing and confidence intervals of these fragility curves, and (4) demonstration, on the basis of dynamic analysis, of effective use of a protective system for fragility enhancement using a representative bridge in the Memphis area.
