SEISMIC VULNERABILITY ASSESSMENT FOR CONCRETE BRIDGES BY DEVELOPING FRAGILITY CURVES

This work focuses on the development of analytical fragility curves for ordinary highway bridges subjected to reverse and strike-slip fault mechanisms and classified in terms of the column height, reinforcement's yield strength and concrete compressive strength. The results show that the column height have significant effect on seismic vulnerability of ordinary highway concrete bridges. Additionally, the reverse fault records produce larger bridge demands than those of the bridges subjected to the strike-slip accelerograms, increasing the seismic vulnerability as well.
