Flexural Stiffness and Crack Width of Partially Prestressed Beams with Unbonded Tendons

open access: yesBuildings, 2023
The original concept of “Total Prestress” consists of creating compressions in concrete without generating tension stresses for service load, while in "Partially Prestressed” elements, tensions are allowed in the service stage, which would produce some ...

A FINITE ELEMENT MODEL FOR THE STUDY OF THE CREEP AND SHRINKAGE EFFECTS IN THE PARTIALLY PRESTRESSED CONTINUOUS COMPOSITE BEAMS

open access: yesTikrit Journal of Engineering Sciences, 2005
A finite element model for the study of the creep, shrinkage and tensile stiffness between cracks effects in partially prestressed continuous composite beams with deformable shear connections is proposed in this paper.

Flexural strengthening of preloaded reinforced concrete continuous beams: An experimental investigation

open access: yesAlexandria Engineering Journal, 2019
This paper investigates experimentally the preloading effect on the flexural behavior of reinforced concrete strengthened continuous beams. Five continuous reinforced concrete beams were tested; they all had the same dimensions and the same reinforcement

FLEXURAL BEHAVIOR OF NORMAL AND HIGH STRENGTH CONTINUOUS BEAMS REINFORCED BY GFRP BARS

open access: yesJournal of Engineering and Sustainable Development, 2021
In the reinforced concrete structures, fiber reinforced polymer (FRP) has been considered an alternative material to steel reinforcement with the advantages of corrosion resistance, non-conductivity, and high strength to weight ratio.

Flexural Strengthening of Continuous RC Beams Using HPFRCC Precast Laminates [PDF]

open access: yesJournal of Structural and Construction Engineering, 2021
In this study, the use of precast laminates, made of high-performance fiber-reinforced cementitious composite (HPFRCC), was investigated for strengthening of continuous reinforced concrete (RC) beams.

Experimental Analysis of Continuous Beams Made of Self-Compacting Concrete (Scc) Strengthened with Fiber Reinforced Polymer (Frp) Materials

open access: yesApplied Sciences, 2021
Strengthening of concrete structures is applied as a solution for various deterioration problems in civil engineering practice. This also refers to the structures made of self-compacting concrete (SCC), which is increasingly in use, but there is a lack ...

“Analytical continuation” of flattened Gaussian beams

open access: yesJournal of the Optical Society of America A, 2023
A purely analytical extension of flattened Gaussian beams [Opt. Commun. 107, 335 (1994)OPCOB80030-401810.1016/0030-4018(94)90342-5] to any values of beam order is here proposed. Due to it, the paraxial propagation problem of axially symmetric, coherent flat-top beams through arbitrary ABCD optical systems can definitely be solved in closed form via a ...

Effects of Internal Force Redistribution on the Limit States of Continuous Beams with GFRP Reinforcement

open access: yesApplied 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 ...
