Dynamic Effects of Turbulent Crosswind on the Serviceability State of Vibrations of a Slender Arch Bridge Including Wind-Vehicle-Bridge Interaction [PDF]

, 2017
The use of high-performance materials in bridges is leading to structures that are more susceptible to wind- and traffic-induced vibrations due to the reduction in the weight and the increment of the slenderness in the deck.

Rocket blast resistance of the fully demountable high performance FRC tongue and groove blocks

Structural Concrete, Volume 25, Issue 2, Page 826-849, April 2024.
Abstract Within the scope of this study, the design and testing of a fully demountable high‐performance fiber‐reinforced concrete (FRC) barriers with high resistance to sudden dynamic explosion and impact loadings is investigated. In order to solve such an engineering problem, a special FRC “tongue and groove” blocks are designed in a way that could be

Shear bond between existing concrete and high‐strength fiber reinforced overlay: Influence of substrate strength and interface roughness

Structural Concrete, Volume 25, Issue 1, Page 526-536, February 2024.
Abstract Bonded concrete overlays are widely used for strengthening and repair of concrete members. The aim of a concrete repair is to restore the load‐carrying capacity and stiffness of a concrete member, and to extend the service life of a structure. The bond between substrate and overlay is one of the main factors concerning the serviceability of a ...

Experimental and theoretical analysis of cracking and tension stiffening in UHPFRC under high‐cycle fatigue

Structural Concrete, Volume 25, Issue 1, Page 379-402, February 2024.
Abstract Tension‐stiffening controls the serviceability behavior of concrete structures as it is responsible for crack formation and, consequently, the deflection of beams. In fiber reinforced concrete, such as ultra‐high performance fiber reinforced concrete (UHPFRC), fibers bridge cracks and thereby transfer tensile stresses across the cracked region,
