“…In RC beams of critical shear forces, increasing the GFRP transverse reinforcement ratio causes an increase in diagonal cracking but with lower crack widths [10]. Shehata (1999) [11] and Ahmed et al [12] urged that the lower tensile strength was assigned for the bent portions of the FRP stirrup than that for the straight portion. Their hypothesis denoted that the anticipated shear failure usually occurs in the bent portion of the FRP stirrups.…”

Fiber-Reinforced Concrete (FRC) is a competitive solution for the durability of reinforced structures. This paper aims to observe moment redistribution behavior occurring due to flexural and shear loading in GFRP reinforced continuous concrete beams. A rectangular cross-section was adopted in this study with dimensions of 200 mm in width and 300 mm in depth with a constant shear span-to-depth ratio of 3. The reinforcement ratio for the top and bottom were equal at sagging and hogging moment regions. A finite element model was created using ANSYS and validated with the existing experimental results in the literature review. Based on the literature review, the parametric study was conducted on twelve beam specimens to evaluate the influence of concrete compressive strength, transversal GFRP stirrups ratio, and longitudinal reinforcement ratio on the redistribution of the moment in beams. Several codes and guidelines adopted different analytical models. The CSA S806 adopted the modified compression field theory in predicting the shear capacity of the simply supported beams. Recently, various researchers encountered several factors and modifications to account for concrete contribution, longitudinal and transverse reinforcement. A comparison between the predicting shear capacity of the generated finite element model and the analytical model and the existing data from literature was held. The generated finite element model showed a good agreement with experimental results while the beam specimens failed in shear after undergoing significant moment redistribution from hogging to sagging moment region.

Aufgrund chloridinduzierter Korrosion müssen Brückenkappen aus Stahlbeton regelmäßig bzw. vielfach häufiger als geplant erneuert werden. Im Rahmen eines vom Bundesministerium für Wirtschaft und Klimaschutz geförderten ZIM‐Projekts wurden Brückenkappen aus einer nichtmetallischen Basaltfaserstabbewehrung und einem Recyclingbeton entwickelt, sodass die Schwachstelle der Korrosion entschärft wird und die Materialien im Hinblick auf den Materialkreislauf zugleich besser ausgenutzt werden. Hierzu wurden gebogene Bewehrungselemente aus chloridunempfindlicher Basaltfaserstabbewehrung sowie ein Beton mit hohem Frost‐Tausalz‐Widerstand entwickelt, der aus bis zu 100 % recyclierter Gesteinskörnung besteht. Alle Teilentwicklungen wurden zu einem ganzheitlichen Ansatz vereint und ein Prototyp einer ressourcenschonenden und dauerhaften Brückenkappe erfolgreich hergestellt und getestet.
