Moment redistribution in continuous FRP reinforced concrete beams [PDF]
Construction and Building Materials, 2013 Abstract The main purpose of this paper is to assess moment redistribution in continuous concrete beams reinforced with fibre reinforced polymer (FRP) bars. A numerical technique based on equilibrium of forces and full compatibility of strains has been developed to evaluate the moment–curvature relationships and moment capacities of FRP and steel ...

Flexural behavior of RC continuous T-beams reinforced with hybrid CFRP/ steel bars (experimental and numerical study) [PDF]
JES: Journal of Engineering Sciences, 2021 This study presents experimental and numerical investigations to understand the response and failure of hybrid RC continuous T-beams reinforced in flexure by both Carbon Fiber Reinforced Polymer (CFRP) bars and steel bars at sagging and hogging regions ...

Moment redistribution effects in beams [PDF]
Magazine of Concrete Research, 2005 Moment redistribution in beams has traditionally been considered as an ultimate limit state (ULS) phenomenon closely associated with considerations of reinforcement ductility. This paper demonstrates that a significant proportion of this redistribution will almost always occur at the serviceability limit state (SLS) because of the mismatch between the

Numerical Assessment on Bonded and Unbonded Prestressed Concrete Beams
Buildings, 2022 The tendon stress in bonded prestressed concrete (BPC) beams is section-dependent while it is member-dependent in unbonded prestressed concrete (UPC) beams, leading to marked difference between these two structural systems.

The effect of moment redistribution on the stability of reinforced concrete moment resisting frame buildings under the ground motion [PDF]
Journal of Structural and Construction Engineering, 2017 In recent years some studies have been done on the moment rredistribution in buildings and new methods offered for calculating of redistribution. Observations demonstrated that the combination of moment and shear force is important in analysis of ...

Prediction of Nonlinear Flexural Behavior of Continuous RC Beams Pre-Damaged by Corrosion
Buildings, 2023 Numerical simulation models capable of predicting the nonlinear flexural behavior of continuous reinforced concrete (RC) beams with corroded reinforcement were developed. Laboratory tests were conducted to validate predictions of the numerical models.

Applied Sciences, 2020 Fiber-reinforced polymers (FRP) are commonly used as internal reinforcement in RC structures in aggressive environments. The design of concrete elements reinforced with FRP bars is usually ruled by serviceability criteria rather than the ultimate limit ...
