چکیده

bridges, as an essential part of transportation system, play a special role in economy, politic and military all around the world. serviceability of bridges is of high importance especially in emergencies, helping injured people and proportioning transportation after earthquakes. earthquake regulation codes, normally suggest linear methods to conduct the analysis, and nonlinear analysis is barely used by practicing engineers. in this paper, we analyze a typical concrete bridge located in iran and use both nonlinear dynamic and static procedures at two hazard levels. this study compares both methodologies, analyze the results and presents some recommendations to reduce the seismic vulnerability.

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...

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 ...

A STUDY ON NONLINEAR BEHAVIOR AND SEISMIC DAMAGE ASSESSMENT OF CONCRETE ARCH DAM-RESERVOIR-FOUNDATION SYSTEM USING ENDURANCE TIME ANALYSIS

In the present paper, nonlinear behavior of mass concrete simulated by smeared crack model is combined with Endurance Time Analysis (ETA) method for studying seismic response of arch dams. ETA is a time-history based dynamic pushover procedure in which special predesigned intensifying acceleration functions are used for analysis and estimation of structural responses in various performance leve...
