Abstract: Providing additional confinement by external fiber-reinforced polymer (FRP) wrapping is one of the most common and effective techniques for the retrofit of existing reinforced concrete columns. Over the past 2 decades, ...

Abstract: Prestressed concrete bridges built as early as the 1950s and still in use have deteriorated as a result of prestress losses, aging, and corrosion. This deterioration necessitates load posting, repair, retrofit, or ...

Abstract: The North Carolina Department of Transportation (NCDOT) identified several mass concrete footings in coastal bridges with cracking that needed to be assessed in the context of current North Carolina mass concrete specifications. ...

Abstract: The use of near surface mounted (NSM) fiber reinforced polymer (FRP) strips for strengthening reinforced concrete structures shows great promise as the strains at intermediate crack (IC) debonding are generally much greater ...

Abstract: This paper presents an experimental investigation on the bond behavior between basalt fiber–reinforced polymer (BFRP) sheet and concrete substrate under the coupled effects of freeze-thaw cycling and sustained load. Test ...

Abstract: A combined experimental and numerical program was conducted to study the in-plane shear behavior of clay brick masonry walls strengthened with near surface mounting carbon-fiber-reinforced polymer (CFRP) strips. This paper ...

Abstract: In this paper the results of 18 pull tests performed on clay brick masonry prisms strengthened with near-surface mounted carbon fiber-reinforced polymer (CFRP) strips are presented. The pull tests were designed to add to ...

Abstract: An experimental investigation was conducted to study the in-plane shear behavior of masonry panels strengthened with near-surface mounted (NSM) carbon fiber-reinforced polymer strips (CFRP). As part of the study four ...
