Retrofitting And Rehabilitation Of Bridge Components Subjected To Predominantly Flexural Load Using Thin Uhpc Shell, Alireza Valikhani
FIU Electronic Theses and Dissertations
The number of bridges exceeding their design life is increasing every year and Federal Highway Administration estimates that structurally deficient and functionally obsolete bridges comprise almost 24% of total bridge inventory in the U.S. Besides aging, the existing bridges can sustain damages due to various factors including exposure to severe environment, deleterious chemicals, and overloading. To avert any catastrophic loss of property and life, it is imperative that the existing bridge inventory is rehabilitated and repaired at a minimal cost and at an expedited schedule using advanced construction methodologies and materials.
One such advancement consists of the use of Ultra-High …

In the United States, ~30% of the ~600,000 highway bridges are categorized as structurally deficient or functionally obsolete. These bridges should be replaced or upgraded to sustain the transportation needs of the growing public and private sectors of the U.S. economy. It is not uncommon for structures to have advanced levels of corrosion-induced damage where major repair and maintenance works are required. However, the transportation infrastructure may undergo disruption during rehabilitation causing interruption to critical economic public, civil and commercial activities. This mandates the development of new techniques and materials for accelerated rehabilitation and resilience. To address this issue, a …
