Influence of fatigue loading and environmental conditions on the bond behavior ...
Mendes, Pedro J. D.; Barros, Joaquim A. O.; Sena-Cruz, José; Taheri, MahsaTo assess the influence of fatigue loading and environmental conditions on the bond behavior between glass fiber reinforced polymer (GFRP) systems and steel fiber reinforced self-compacting concrete (SFRSCC) that are adhesively bonded, an experimental program composed of push-out tests was carried out. The following three scenarios were selected for the environmental conditions: natural conditions; wet-dry cycl...
Assessment of the potentialities of recycled steel fibres for the reinforcement...
Barros, Joaquim A. O.; Zamanzadeh, Z.; Mendes, Pedro J. D.; Lourenço, LúcioRecent research is evidencing that adding steel fibres recycled from wasted tires can improve the post-cracking behaviour of cement based materials, enhancing the ductility, energy dissipation and impact resistance of elements made by this type of composites. As a consequence, Recycled Steel Fibre Reinforced Concrete (RSFRC) appears as a promising candidate for both structural and non-structural applications. T...
Steel fibre reinforced self-compacting concrete for lightweight and durable ped...
Mendes, Pedro J. D.; Barros, Joaquim A. O.; Gonçalves, Delfina; Sena-Cruz, JoséIn recent years, pedestrian bridges built from composites materials have notably increased. This growth is related to the durability problems of traditional materials, as well as the need for fastest construction times. In this context, fiber reinforced concrete (FRC) becomes an important material in this type of structures, since the ductility, high post-cracking tensile strength, high compressive stiffness an...
A design model for fibre reinforced concrete beams pre-stressed with steel and ...
Barros, Joaquim A. O.; Taheri, Mahsa; Salehian, Hamidreza; Mendes, Pedro J. D.This paper presents a design oriented model to determine the moment-curvature relationship of elements of rectangular cross section failing in bending, made by strain softening or strain hardening fibre reinforced concrete (FRC) and reinforced with perfectly bonded pre-stressed steel and fibre reinforced polymeric (FRP) bars. Since FRP bars are not affected by corrosion, they have the minimum FRC cover thic...
Development of a pedestrian bridge with GFRP profiles and fibre reinforced self...
Barros, Joaquim A. O.; Mendes, Pedro J. D.; Sena-Cruz, José; Taheri, MahsaIn recent years, the number of pedestrian bridges built from composites materials has notably increased. The combination of fiber reinforced polymers (FRP) profiles with fiber reinforced concrete (FRC) elements is being adopted in this type of structures, since the ductility, high post-cracking tensile strength, compressive stiffness and strength of FRC can be combined with the benefits derived from the use of ...
