BOND AND SHEAR-STRENGTHENING PERFORMANCE OF FRCM COMPOSITES

open access: yesProceedings of International Structural Engineering and Construction, 2019
This paper is aimed at studying the bond and shear-strengthening performance of fabric reinforced cementitious matrix (FRCM) systems. Three FRCM systems were compared, namely, polyparaphenylene benzobisoxazole (PBO)-FRCM, Carbon-FRCM, and Glass-FRCM. At first, six double-shear specimens were tested to investigate the FRCM/concrete bond, with the test ...

An experimental investigation for external RC shear wall applications [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2010
The strength and rigidity of most reinforced concrete (RC) buildings in Turkey, which are frequently hit by destructive earthquakes, is not at a sufficient level. Therefore, the result of earthquakes is a significant loss of life and property.

FRP strengthening of shear walls with openings [PDF]

open access: yes, 2011
Concrete shear walls are one of the main lateral resisting members in buildings. The functional requirements like architectural and even mechanical requirements entail that openings have to be installed in structural walls as well as floors. In this study, nonlinear static analysis was utilized to study the effects of fiber reinforced plastic (FRP) on ...

Slabs strengthened for punching shear with post-installed steel and CFRP connectors

open access: yesRevista IBRACON de Estruturas e Materiais, 2019
Structural accidents due to punching shear failures have been reported in flat slab buildings. Design recommendations presented by codes can lead to entirely different punching shear resistance estimates for similar situations.

Size Effect in FRP Shear-Strengthened RC Beams: Design Models versus Experimental Data

open access: yesCivilEng, 2021
Numerous studies on the size effect have been devoted to reinforced concrete (RC) beams. They have shown that increasing the beam size leads to a decrease in ultimate shear strength (stress) at failure.
