Reinforced concrete beams strengthened in shear with NSM CFRP laminates : assessment of influencing parameters [PDF]

open access: yes, 2013
To appraise the performance of the Near surface mounted (NSM) technique with carbon fiber reinforced polymer (CFRP) laminates for the shear strengthening of reinforced concrete (RC) beams having a certain percentage of existing steel stirrups, an ...

FRCM/internal transverse shear reinforcement interaction in shear strengthened RC beams

open access: yesComposite Structures, 2018
Abstract This paper presents a study on the efficacy of a shear strengthening technique utilizing fabric reinforced cementitious matrix (FRCM) systems for beams with and without internal transverse shear reinforcement (ITSR) within the critical shear span (CSS). The paper focuses on the FRCM/ITSR interaction, experimentally and analytically.

Optimisation of shear strengthened reinforced concrete beams [PDF]

open access: yesProceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, 2014
External prestressed carbon fibre reinforced polymer straps can be used to strengthen shear-deficient reinforced concrete structures. For an efficient shear retrofitting system, the optimum combinations of parameters such as the number of straps, strap locations, strap stiffness and initial strap prestress need to be identified.

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

open access: yesAdvanced Functional Materials, EarlyView.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.

Embedded through-section bars for the shear strengthening of RC beams [PDF]

open access: yes, 2012
Embedded Through-Section (ETS) technique is a relatively recent shear strengthening strategy for reinforced concrete (RC) beams, and consists on opening holes across the beam thickness, with the desired inclinations, where bars are introduced and are

Frictional behavior of talc-calcite mixtures [PDF]

open access: yes, 2015
Faults involving phyllosilicates appear weak when compared to the laboratory-derived strength of most crustal rocks. Among phyllosilicates, talc, with very low friction, is one of the weakest minerals involved in various tectonic settings.

Experimental Study on Shear Strengthening of RC Beams with an FRP Grid-PCM Reinforcement Layer

open access: yesApplied Sciences, 2019
This paper investigates the shear strengthening effect of a number of reinforced concrete (RC) beams strengthened by a reinforcement layer which combines carbon fiber reinforced polymer (CFRP) grid and polymer cement mortar (PCM). A total of ten RC beams,
