Abstract: Formulation of the mobilized force-displacement-capacity for the seismic design of a bridge abutment–embankment system is presented herein. As part of the seismic design philosophy of bridge structures, a realistic prediction ...

Abstract: Current seismic design of bridges is based on a displacement performance philosophy using nonlinear static pushover analysis. This type of bridge design necessitates that the geotechnical engineer predict the resistance ...

Abstract: Although rammed aggregate piers (RAPs) have attracted much attention as a cost-beneficial ground improvement technique, their construction process and the other affecting parameters on the behavior of these geotechnical ...

Abstract: Abutment-backfill soil interaction can significantly influence the seismic response of bridges. In the present study, we provide numerical simulation models that are validated using data from recent experiments on the ...

Abstract: Presence of skew-angled abutments complicates the seismic behavior of ordinary bridges, primary effect of which is the passive lateral resistance of the engineered backfill behind the abutment. The eccentricity of the soil ...

Abstract: Bridge abutments typically contain a backwall element that is designed to break free of its base support when struck by a bridge deck during an earthquake event and push into the abutment backfill soils. Results are presented ...

Abstract: In this study, a lightweight prestressed steel jacket (PSJ) was proposed and developed for rapid and cost-effective repair of a severely damaged circular reinforced concrete column. The PSJ is composed of several prestressed ...

Abstract: California’s high-speed rail (HSR) system is slated to traverse nearly the entire length of the state, and thus it will be exposed to seismic risks from almost every known major tectonic fault there. The present study deals ...

Abstract: The StreetScan pavement-management system (PMS) is introduced. It empowers cities to make more cost-effective road repair decisions. At the heart of the system is a vehicle outfitted with a patented, multimodal sensor array ...
