Steel fiber reinforced concrete (SFRC) has been increasingly used during recent years. Regarding bond of rebars to concrete, fibers provide passive confinement and improve bond capacity in terms of bond strength and, more ...
García Taengua, Emilio José(Universitat Politècnica de València, 2013-10-21)
The use of steel fiber reinforced concrete (SFRC hereafter) is becoming more and more
common. Building codes and recommendations are gradually including the positive effect of
fibers on mechanical proper ...
In pretensioned concrete members, strand bond is necessary for transferring prestress force from the prestressing strands to the adjacent concrete. This paper proposes a new bond stress-slip model for 0.6 in. (15.2 mm), ...

Martí Vargas, José Rocío; Serna Ros, Pedro; Navarro Gregori, Juan; Bonet Senach, José Luís(Elsevier, 2012)
The bond behaviour of prestressing strands in precast pretensioned concrete members, and its transmission length, depends on several factors. However, no consensus exists on the main parameters to be considered in the ...
[EN] This paper presents a study on the flexural behavior of Ultra-High-Performance Fiber-Reinforced Concrete (UHPFRC) beams, which included conventional reinforcing bars. The study focuses on critical design aspects, such ...
