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 ...

Development of Fragility and Reliability Curves and Seismic Vulnerability Evaluation of Talehzang Concrete Bridge

Bridges are potentially one of the most seismically vulnerable structures in the highway system during earthquake &#10 &#10events. It is known that the seismic performance of transportation systems plays a key role in the post-earthquake emergency management. Hence, it is necessary to evaluate both physical and functional aspects of bridge structures. The physical aspects of the seismic perform...

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...

Time-dependent Seismic Fragility Curves on Optimal Retrofitting of Neutralized Reinforced Concrete Bridges

Probabilistic Approach to the Seismic Vulnerability of RC Frame Structures by the Development of Analytical Fragility Curves

Fragility curves are very useful in quantifying the physical and economic damage of buildings that have undergone an earthquake. This paper presents the development of analytical fragility curves representative of mid-rise residential structures built with reinforced concrete, taking into account the specific structural characteristics of Algerian buildings. The derivation of the analytical fra...
