Effect of FRP Anchors on the FRP Rehabilitation of Shear Twenty one shear critical RC beams were strengthened in shear with u-wrapped FRP sheets and FRP anchors. Eight RC one-way slabs were strengthened in flexure with FRP sheets and FRP anchors. The test variables include the type of FRP sheets (GFRP,CFRP), type of FRP anchors (CFRP, GFRP) and the strengthening configuration. The test results of the

Flexural Strengthening of RC Slabs Using a Hybrid FRP For the retrofitted RC slabs, three shear connectors were located as shown in Figure 4.Number 10 rebars having the area of 71 mm 2 were used for the shear connectors. 4-CFRP sheets were installed and concrete having the 28-day compressive strength of 79 MPa was overlaid. The strength and elastic modulus of CFRP are 600 MPa and 40 GPa, respectively.

Flexure-Shear Analysis of Concrete Beam Reinforced with The influence of vertical reinforcement ratio, longitudinal reinforcement ratio and compressive strength of concrete on shear strength of GFRP reinforced concrete beam is studied. The critical value of shear span to depth ratio (a/d) at which the mode of failure changes from flexure to shear is studied.

Punching Shear Strength of GFRP-Reinforced Flat Slabs Structures:Experimental and analytical approach Serviceability and ultimate behaviour of GFRP reinforced May 01, 2020 · However, they experienced larger deflections under the same load and had a lower ultimate shear strength than the NWC slabs. A reduction factor was found to be necessary for predicting shear strength when the LWC is used with GFRP bars. Liu and Pantelides [30], [31] investigated the capacity of LWC/GFRP slabs in terms of shear strength.

Shear Performance of Reinforced Concrete Beams with GFRP

In this study, "Glass Fiber Reinforced Polymers GFRP" has tested for shear performance, where a practical program has applied. Three "simply supported beams" as control specimens have been prepared and tested, with the other nine beams with different combinations of reinforcement of steel and GFRP for flexure and shear resistance. Shear Strength of FRP RC Beams and One-Way Slabs without Shear Strength of FRP RC Beams and One-Way Slabs without Stirrups a generic closed-form solution is derived for quantifying the shear capacity of RC beams and one-way slabs without stirrups and in theory with any type of reinforcement and concrete. The model is validated with 209 published shear tests of FRP-reinforced specimens with normal Shear Strength of GFRP Reinforced Concrete Masonry BeamsAs shear design eions in most of the masonry design codes, such as TMS 402-2016 code, are intended to be used for designing masonry beams reinforced with conventional steel, the test results showed that these eions can yield unsafe shear predictions for GFRP-reinforced or high-strength steel-reinforced masonry beams.

For the first-ordereion, the average ratio of experimental-to- predicted shear strength for normaiweight concrete slabs is 2.14, with a COV of 9.2%; the average ratio for lightweight concrete slabs is Shear strength of GFRP reinforced precast lightweight Nov 01, 2013 · The shear capacity of normal weight concrete beams or slabs reinforced with GFRP bars without transverse shear reinforcement has been investigated , , , , , , , , , , , , . In these studies, normal weight concrete of either normal or high strength was used; in addition, all members failed in one-way shear. Size effect on shear strength of concrete beams size glass FRP (GFRP) RC beams tested to date, as part of an extensive research program, are presented and discussed on the basis of the shear strength con-tribution of the concrete, Vc, and of the transverse re-inforcement, Vf. The results indicate the presence of strong size effect on the former. Analysis of the pre-
