SEISMIC FRAGILITY CURVE THEORY FOR HIGHWAY BRIDGES

摘要

The principal objective of this research was to develop, from the fundamentals of mechanics and dynamics, the theoretical basis of establishing fragility curves for highway bridges through the use of rapid analysis procedures. In contrast to other methods that have been used in the past, such as either empirical/experiential fragility curves or individualized fragility curves based on extensive computational simulations, the present approach seeks to establish dependable fragility curves based on limited data obtainable only from the National Bridge Inventory.
