Efficacy of NSM hybrid FRP strips for shear strengthening of rc deep beams
(
University of Cantabria - Building Technology R&D Group
, 2020 , Conference Paper)
This paper presents an experimental study on the efficacy of near-surface mounted (NSM) hybrid carbon/glass fiber reinforced polymer (FRP) strips for the strengthening of shear-critical reinforced concrete (RC) deep beams. ...
Engineering students' conceptions of collaboration, group-based strategy use, and perceptions of assessment in PBL: A case study in Qatar
(
Tempus Publications
, 2020 , Article Review)
This study has investigated the natures of collaboration, group-based strategy use, and perception of assessment, as well as interactions among these aspects, by examining group performance in engineering students' first ...
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 ...
Long-Term Cost Performance of Corrosion-Resistant Reinforcements in Structural Concrete
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Corrosion, which leads to the premature deterioration of reinforced concrete (RC)
structures, is increasingly an issue of global concern. Accordingly, corrosion-resistant
materials have emerged as alternative reinforcement ...
Steel Reinforced Grout for Strengthening of RC T-section Beams Deficient in Shear
(
Qatar Univesrity Press
, 2020 , Conference Paper)
numerous causes. Thus, proper strengthening and rehabilitation techniques are required
to restore the strength and extend the service life of the structures. Steel reinforced
grout (SRG) has recently been introduced as an ...
Effects of Using Seawater and Recycled Coarse Aggregates on Plain Concrete Characteristics
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Using seawater and/or recycled coarse aggregates (RCA) for concrete mixing is deemed
advantageous from a sustainability perspective. This paper reports on the results of an
experimental study on fresh and hardened properties ...
