A QUANTITATIVE APPROACH FOR RAPID SEISMIC VULNERABILITY ASSESSMENT OF STEEL HIGHWAY BRIDGES

While methodologies exist which allow to rapidly identify the seismically deficient bridges and rank them in terms of their respective vulnerability, it remains that the bridge vulnerability aspect of these methodologies is crude and generally limited to simple recognition of undesirable structural features known to have performed inadequately in past earthquakes. Thus, bridges sharing such features would also share the same rating, independently of variations in geometry and other structural properties. As one step to improve on this situation, a methodology is proposed to perform rapid, yet quantitative, seismic vulnerability assessments. It was developed and applied for a special class of bridges, namely single-span and multi-span slab-on-girder highway steel bridges. In the latter case, only steel columns were considered, as these have received little attention in past research.
