Experimental Investigation on the Seismic Performance of Horizontally Curved Bridges (NEES-2010-0967)

<p><strong>Title:</strong> Experimental Investigation on the Seismic Performance of Horizontally Curved Bridges (NEES-2010-0967)</p> <p><strong>Year Of Curation: </strong>2014</p> <p><strong>Description: </strong>This project is a task within a larger project funded by Federal Highway Administration (FHWA) under a contract to the University of Nevada to study the seismic resilience of highway systems. It is the objective of this Project to conduct a comprehensive study of the seismic response of horizontally-curved highway bridges. The ultimate aim is to develop a set of seismic design guidelines for this type of bridge. A secondary aim is to develop a set fragility functions for curved bridges for use in resilience studies of highway systems. The scope therefore includes numerical analyses, parameter studies, and large-scale, shake table experiments on a highly curved bridge to investigate load path in the superstructure, column behavior, abutment interaction (pounding), and the effectiveness of response modification devices, self-centering substructures, and rocking columns. Design guidelines and fragility functions will be developed. Whereas the numerical studies will be conducted for a wide range of curved geometries and structure types, the experimental studies will be on a large-scale model of a highly curved, continuous bridge, with a steel superstructure supported on concrete piers and seat-type abutments.</p> <p><strong>Award: </strong>Caltrans 59A0695FHWA DTFH61-07-C-0003</p> <p><strong>PIs & CoPIs: </strong>Ian Buckle, Ahmad Itani, David Sanders</p> <p><strong>Dates: </strong>November 02, 2009 - April 30, 2013</p> <p><strong>Organizations: </strong> N/A</p> <p><strong>Facilities: </strong>University of Nevada-Reno, NV, United States</p> <p><strong>Sponsor: </strong>Caltrans - 59A0695</p> <p><strong>Keywords: </strong>Shake Table, Curved Bridge, Seismic Isolation, Seismic Response, Steel Plate Girder Bridge, live load, Hybrid Isolation, Abutment Interaction, rocking foundation</p> <p><strong>Publications: </strong></p> <p>"Seismic Performance of Curved Steel Plate Girder Bridge with Seismic Isolation"</p> <p>"Assessment of Foundation Rocking Behavior in Reducing the Seismic Demand on Horizontally Curved Bridges"</p> <p>"The Effect of Live Load on the Seismic Response of Bridges"</p> <nb:citations></nb:citations>
