U-shaped frcm for strength and deformation enhancement of reinforced concrete beams
(
University of Cantabria - Building Technology R&D Group
, 2020 , Conference Paper)
The strength and deformation performances of fabric-reinforced cementitious matrix (FRCM Uwrapped reinforced concrete (RC) beams has been studied in this work. Nine RC beams were used to assess this strengthening technique, ...
Short-term flexural performance of seawater-mixed recycled-aggregate GFRP-reinforced concrete beams
(
Elsevier
, 2020 , Article)
Combining seawater, recycled coarse aggregate (RCA), and glass fiber reinforced polymer (GFRP) reinforcement in concrete is potentially advantageous from a sustainability perspective. This paper reports on the results of ...
Flexural strengthening of reinforced concrete beams using hybrid near-surface embedded/externally bonded fabric-reinforced cementitious matrix
(
Elsevier
, 2020 , Article)
The efficacy of hybrid near-surface embedded/externally bonded (NSE/EB) fabric-reinforced cementitious matrix (FRCM) for flexural strengthening of reinforced concrete (RC) beams was assessed experimentally. Bending tests ...
Shear capacity of reinforced concrete deep beams using genetic algorithm
(
IOP Publishing Ltd
, 2020 , Conference Paper)
It is vital to understand the shear behaviour of reinforced concrete (RC) beams in order to avoid a catastrophic shear failure and design for ductile failure. However, due to the complexity in the shear failure mechanism ...
Comparing models of problem and project-based learning (PBL) courses and student engagement in civil engineering in Qatar
(
Modestum LTD
, 2020 , Article)
Background: While improved student engagement has been highlighted as an essential goal and a major outcome of Problem and Project-Based learning (PBL), little empirical evidence has been provided regarding types and forms ...
Impact of high turbidity on reverse osmosis: Evaluation of pretreatment processes
(
Desalination Publications
, 2020 , Article)
This study evaluates the performance of sand filtration (SF) and ultra-filtration (UF) as pretreat-ment processes for reverse osmosis (RO) for seawater with turbidities of 4.8, 23.2, and 99.7 NTU. For seawater with a ...
Investigating nonlinear forced vibration behavior of multi-phase nanocomposite annular sector plates using Jacobi elliptic functions
(
Techno-Press
, 2020 , Article)
A multi-scale epoxy/CNT/fiberglass annular sector plate is studied in this paper in the view of determining nonlinear forced vibration characteristics. A 3D Mori-Tanaka model is employed for evaluating multi-scale material ...
Nonlinear forced vibrations of multi-scale epoxy/CNT/fiberglass truncated conical shells and annular plates via 3D Mori-Tanaka scheme
(
Techno-Press
, 2020 , Article)
In the context of classic conical shell formulation, nonlinear forced vibration analysis of truncated conical shells and annular plates made of multi-scale epoxy/CNT/fiberglass composites has been presented. The composite ...
Assessment of transient vibrations of graphene oxide reinforced plates under pulse loads using finite strip method
(
Techno Press
, 2020 , Article)
Based on a refined shear deformation finite strip, transient vibrations of graphene oxide powder (GOP) reinforced plates due to external pulse loads have been investigated. The plate has uniformly and linearly distributed ...
Electrochemical behavior of mild and corrosion resistant concrete reinforcing steels
(
Elsevier
, 2020 , Article)
An experimental study is carried out in this paper to evaluate the corrosion performance of mild steel reinforcing bars (MS), high strength steel reinforcing bars (HS), epoxy-coated steel reinforcing bars (EC), and ...
