Fragility Curve Development for Assessing the Seismic Vulnerability of Highway Bridges (1997-1999)
نویسنده
چکیده
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 of data are needed for this analysis: (1) National Bridge Inventory (NBI) records that contain the bridge attributes and geographical location; (2) ground motion data (this is best obtained from the USGS web site); and (3) geological maps from which soil types and hence S-factors can be inferred. Full details of this approach are given in Basöz and Mander (1999). by John B. Mander, University at Buffalo, State University of New York

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 ...

متن کاملProbabilistic Evaluation of Seismic Performance of RC Bridges in Iran
Many existing bridges were designed without adequate consideration of seismic risk. The full or partial collapse of even one major bridge in a city or community would have destroying results. There has been focuses on developing fragility-based seismic vulnerability of existing usual bridges in Iran or support decision making on seismic upgrade. This article focuses on developing performance b...
متن کاملThe Effect of Compressive Strength Reduction of Column Section Expose due to Freezing-Thawing Cycles on the Seismic Performance of Bridges
One of the serious damages of tremendous earthquakes is the damage to bridges as the major components in an arterial road network, as relief operation is interrupted following cutting roads. Regardless of the magnitude and severity of an earthquake, other factors are also important in the strength and seismic performance of concrete bridges. Freezing-thawing cycles are among the factors, whi...
