Abstract: Continuous and semicontinuous castellated composite beams can present a global buckling mode in the hogging-moment regions known as lateral-distortional buckling. In this mode, the lower portion of a steel section is ...

Abstract: This paper describes an experimental investigation aimed at retrofitting hot-rolled steel (HRS) channels using cold-formed steel (CFS) sections. Six simply supported specimens were tested under four-point monotonic loading. ...

Abstract: A railway bridge over the Paraopeba River was built in Moeda, Minas Gerais, Brazil; however, the railway line for which it was intended was deactivated and, to reuse it as a road bridge, a concrete deck was installed. Upon ...

Abstract: This paper addresses the dynamic behavior of the La Scarpe viaduct, which consists of a continuous nine-span steel–concrete composite bridge belonging to the French HSR line TGV Nord. The main objective of the paper is to ...

Abstract: The historic Imperial Dom Pedro II Bridge, located in Bahia, Brazil, underwent a major rehabilitation program that began in 2018. All tensioned diagonals, made of puddled iron, were replaced with new components, made of ...

Abstract: This paper presents an experimental study on the strengthening of rectangular timber beams under monotonic loading. Both flexural and shear behavior of the specimens was studied. A total of five timber beam specimens with ...

Abstract: This paper presents the structural behavior of transmission line cables under nondeterministic dynamic wind loads (atmospheric turbulence), considering aerodynamic damping and geometric nonlinearity. A numerical methodology ...

Abstract: The Hercílio Luz Bridge is an eyebar suspension bridge with a riveted girder built in 1926 in Brazil, in which severe fatigue damage was found after years of service. To provide guidance for rehabilitation of the bridge, ...
