“…high strength and stiffness to weight ratio, corrosion resistance, ease and speed of application), the FRP strengthening technique entails several drawbacks, i.e., poor behaviour at moderate to high temperatures, combustibility, high costs, and safety-hazards for the manual workers. These are related to the properties of the organic resins used to impregnate the fibres as for example these have been reported to deteriorate for temperatures below or close to their glass transition temperature (usually in the range of 50-120 0 C), see, e.g., [55,56]. Epoxy-resins furthermore decompose thermally, releasing heat, smoke, soot and toxic/ combustible volatiles for temperature between 300-400 0 C. Compared to wet lay-up epoxy-resin applications, TRM strengthening costs are lower due to the low-cost cement mortars utilized.…”

The out-of-plane response of masonry walls strengthened with textile-reinforced mortar (TRM) is experimentally investigated in this work. Medium-scale three-point bending tests were carried out on 18 specimens comprising a set of 9 single-wythe and 9 double-wythe brick masonry walls. Key investigated parameters involved the textile reinforcement ratio, the textile material, the coating of the textile reinforcement with epoxy resin, and the wall thickness. Experimental results suggest that TRM significantly increase the load bearing capacity of masonry walls. The amount of reinforcement utilised affects both the strength and deformation characteristics of the corresponding specimens, while it may alter the failure mode. Resin coating on the textile is found to be beneficial for the performance of the TRM overlays.

“…One of the methods that was proposed in the literature to reduce the TSR amount was to use a fiber-reinforced polymer (FRP) stay-in-place form to provide extra external confinement [9,10]. The main disadvantage of using FRP stay-in-place forms is their low fire resistance [11][12][13]. Studies have shown that for moderately high temperatures, the polymer of the FRP reaches its glass transition temperature and changes from a brittle to viscous material [13].…”

The standard requirements for transverse steel reinforcement (TSR) confinement in reinforced-concrete (RC) columns are mainly to provide the following: ductile behavior, minimum axial load capacity of the column’s core, and prevention of longitudinal bars buckling. It is well-known that the passive confinement due the TSR action is less effective in high-strength concrete (HSC) compared to normal-strength concrete (NSC). Therefore, the TSR amounts required by the standards for HSC columns are high, and in some cases, especially in the lower stories columns of high-rise buildings, are impractical. This paper presents a new construction method using textile-reinforced concrete (TRC) as internal confinement together with reduced TSR amounts. Moreover, comparison of the proposed method with RC columns casted in fiber-reinforced polymer (FRP) stay-in-place forms as additional external confinement, is presented. Eleven large-scale column specimens were tested under axial compression. The results give an insight on the application feasibility of the proposed construction method. It is shown that the TRC-TSR dual internal confinement action can be an option to reduce the standard required TSR amounts while maintaining similar levels of ductile behavior.
