“…The earlier research reported in References 5–10 concluded that EB‐FRP enhanced the shear and flexural capacity of RC beams. Nawaz et al 12 studied one control and two shear‐deficient self‐compacted concrete beams internally reinforced with GFRP bars that were strengthened in shear with CFRP strips.…”

The reinforced concrete (RC) beams could be upgraded in shear using steel and fiber‐reinforced polymer (FRP) having several shapes (bars, strips, or sheets). Using near‐surface mounted (NSM) Glass FRP (GFRP) bars is still limited compared to carbon FRP (CFRP) elements as shear reinforcement. Moreover, using reinforced high‐strength concrete layers (HSCL) as NSM shear strengthening for the RC beams is still limited. Herein, three RC beams internally reinforced in shear using different shear areas (without, 100 mm stirrups apart, and 200 mm stirrups apart) were experimentally tested as reference beams (CB). Other eight beams strengthened in shear using NSM HSCL, and bars were experimentally tested. Moreover, an extended finite element (FE) simulation was implemented through a verified FE model to study the effect of other NSM aspects on shear‐strengthened beam response. The results explained that, regardless of the internal stirrups area and external NSM characteristics, the shear‐strengthened beams showed higher load efficiency than the corresponding CB. The NSM upgraded shear beam had slightly higher load efficiency than the un‐strengthened beam having the same steel area as internally shear stirrups. Moreover, increasing the internal shear stirrups decreased the total efficiency of the NSM shear strengthening and the internal stirrups regardless of the NSM characteristics. Furthermore, the NSM HSCL was more efficient than the corresponding NSM bars in increasing the load capacity and stiffness of the shear‐strengthened beams. The reported analytical model predicted well the shear capacity of the tested beams.

“…The global behaviour of the RC beams repaired with TRC is quite similar to those repaired by CFRP, e.g., the ultimate strength gains obtained with the TRC reinforcement can reach 38% [ 112 ]. U-wrapping CFRP strip and TRC were, respectively, used to strengthen the shear capacity of short-span concrete beams reinforced with GFRP bars [ 113 ]. The test results showed that the shear strength of specimens strengthened with TRC and CFRP increased by about 33.7% and 12.1%, respectively [ 113 ].…”

Textile reinforced concrete (TRC) is an innovative structure type of reinforced concrete in which the conventional steel reinforcement is replaced with fibre textile materials. The thin, cost-effective and lightweight nature enable TRC to be used to create different types of structural components for architectural and civil engineering applications. This paper presents a review of recent developments of TRC. In this review, firstly, the concept and the composition of TRC are discussed. Next, interfacial bond behaviour between fibre textile (dry and/saturated with polymer) and concrete was analysed considering the effects of polymer saturation, geometry and additives in polymer of the textile. Then, the mechanical properties (including static and dynamic properties) of TRC were reviewed. For static properties, the mechanical properties including compression, tension, flexural, shear and bond properties are discussed. For dynamic properties, the impact, seismic and cyclic properties were investigated. Furthermore, the durability of TRC under different environmental conditions, i.e., temperature/fire, humidity and wet–dry cycles, freeze–thaw, chemical and fatigue were discussed. Finally, typical engineering applications of TRC were presented. The research gaps which need to be addressed in the future for TRC research were identified as well. This review aims to present the recent advancement of TRC and inspire future research of this advanced material.

Torsional tests for four concrete beams reinforced with glass fiber reinforced polymer (GFRP) bars as torsional longitudinal reinforcements and glass textile grids as torsional transverse reinforcements are conducted to study the possibility in using noncorrosive and cold‐bendable glass textile grids as minimum torsional transverse reinforcements. These beams are compared with three control beams reinforced with GFRP torsional transverse reinforcements. Two investigated variables in this experimental study are the number of layers of textile grids and the orientation of torsional transverse reinforcements. Grade 40 fine‐grained concrete is used for all tested beams. A standard pure torsional test is used to study the torsional behaviors of these beams. The experimental behaviors of the tested beams are compared in terms of recorded torque‐twist curves; strain gauge readings in transverse, longitudinal reinforcements, and concrete at critical positions; observed cracking patterns and failure modes. The experimental results are compared with the recommendations for minimum torsional transverse reinforcements in the existing design codes and guidelines such as the ACI 318‐19, EC2, ACI 440.1R‐15, and CSA S806. The comparison indicates that the existing guidelines are unsafe in estimating the minimum transverse torsional reinforcements for glass textile‐reinforced concrete beams.
