The feasibility of using ultra-high performance concrete (UHPC) to strengthen RC beams in torsion

open access: yesJournal of Materials Research and Technology, 2023
To explore the feasibility of using ultra-high performance concrete (UHPC) to strengthen reinforced concrete (RC) beams in torsion, pure torsion tests on 9 specimens have been conducted in this study, including one RC beam without strengthening (referred

Development of Crack Width Prediction Models for RC Beam-Column Joint Subjected to Lateral Cyclic Loading Using Machine Learning

open access: yesApplied Sciences, 2021
In recent years, researchers have investigated the development of artificial neural networks (ANN) and finite element models (FEM) for predicting crack propagation in reinforced concrete (RC) members. However, most of the developed prediction models have

Tapered Polymer Fiber Sensors for Reinforced Concrete Beam Vibration Detection

open access: yesSensors, 2016
In this study, tapered polymer fiber sensors (TPFSs) have been employed to detect the vibration of a reinforced concrete beam (RC beam). The sensing principle was based on transmission modes theory.

Numerical Investigation on the Dynamic Responses and Failure Criterion of RC Beam Under Impact

open access: yesFrontiers in Materials, 2022
During the period of service, the infrastructure is subjected to various forms of impact. To investigate the impact responses of a reinforced concrete (RC) beam, a numerical model of the RC beam under impact was developed by the finite element package LS-

Cyclic behavior of a two-span RC beam built with plain reinforcing bars [PDF]

open access: yes, 2011
Reinforced concrete structural elements lacking appropriate seismic detailing and built with plain reinforcing bars, and subjected to cyclic loads like the ones induced by earthquakes, are particularly sensitive to the bond-slip mechanism.

OPTIMIZATION OF SINGLY REINFORCED RC BEAMS

open access: yesInternational Journal of Research -GRANTHAALAYAH, 2017
The main objective of this paper is to achieve an optimal design for the reinforced concrete beams. Optimization of beams results in saving in cost. The objective function is to minimize the total cost of the beam. The cost of each beam includes the cost of concrete, reinforcement and formwork.

Analysis of FRP shear strengthening solutions for reinforced concrete beams considering debonding failure [PDF]

open access: yes, 2016
In this paper, a fiber beam model previously developed by the authors for the nonlinear analysis of strengthened elements, including the effects of shear, is used to predict the response of reinforced concrete (RC) beams strengthened in shear with fiber ...
