Shear design of reinforced concrete beams with FRP longitudinal and transverse reinforcement

Querkrafttragfähigkeit von Carbonbeton‐Plattenbrücken mit C‐förmiger Querkraftbewehrung

“…Aufbauend auf Erfahrungen bei den Fußgängerbrücken in Albstadt‐Lautlingen und Albstadt‐Ebingen wurde auch für diese Projekte eine vertikal stehende textile Gitterbewehrung als Querkraftbewehrung vorgeschlagen. Die Vorbemessung der erforderlichen Bewehrungsmenge erfolgte durch die Firma solidian GmbH unter Verwendung des Modells nach und Berücksichtigung konstruktiver Gesichtspunkte (z. B. dem Maximalabstand in Querrichtung) in Abstimmung mit dem IMB der RWTH.…”

The compression chord capacity model for the shear design and assessment of reinforced and prestressed concrete beams

“…The different models are not contradictory; in fact, the fundamental difference is that they This paper deals with the simplification of a multiaction mechanical model for the shear design and assessment of RC and PC beams previously developed by the authors, which is valid for reinforced concrete and for prestressed concrete members with any degree of prestressing, with or without stirrups, for normal or high strength concrete, and for T, I or rectangular sections [23][24][25]. The predictions of the original mechanical model were compared with four large databases of tests results on RC and PC beams developed by ACI-DafStb [26][27][28], showing small bias and scatter, and have also been extended to FRP RC beams [29,30]. However, for design purposes, some simplifications are still necessary in order to make the mechanical model easier to use in daily engineering practice.…”

Impact and corrosion resistances of duplex epoxy/enamel coated plates

“…For example, the properties of concrete can be modified by applying inhibitors [10,11], reducing water-cement ratio, adding high performance admixtures [12][13][14], and optimizing aggregate gradation. Corrosion resistant bars include non-metallic bars such as fiber reinforced polymer (FRP) bars [15,16], stainless steel bars, stainless steel or copper clad steel bars [17], and coated steel bars [18,19]. Coating is one of the most effective methods to protect steel bars from corrosion by establishing a chemical and physical barrier between the steel and its corrosive environment.…”
