AN INSPECTION METHOD OF SEISMIC VULNERABILITY OF EXISTING HIGHWAY BRIDGES

A methodology for Determining the Seismic Vulnerability of Old Concrete Highway Bridges by Using Fragility Curves

Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...

FE Based Vulnerability Assessment of Highway Bridges Exposed to Moderate Seismic Hazard

Fragility Curve Development for Assessing the Seismic Vulnerability of Highway Bridges (1997-1999)

The purpose of this research is to set forth the basis for developing fragility curves that can be used in various ways as part of a seismic vulnerability analysis methodology for highway bridges. To develop a set of fragility curves for various damage states for a specific bridge, the notion of adjusting “Standard Bridge” fragility curves for sitespecific effects is adopted. Only three sources...

Seismic Vulnerability Study of the Us Highway Bridge Systems

In the fall of 1998, the Federal Highway Administration of the U.S. Department of Transportation initiated a series of studies related to the seismic performance of the U.S. national highway system. The research conducted under this study is intended to provide improved tools for evaluating and assessing the social costs and impacts of earthquakes on highway systems and bridges, and to reduce t...
