“…Serious attention has been paid to stress–strain analysis, failure modes, and determination of shear moduli of such structures and elements as beams; 64,314,315,317,318 beams and structures reinforced/retrofitted with pultruded elements by means of internal or external reinforcement; 319–325 box beams; 326 bridge decks; 31,258,327,328 columns; 286,307 connectors; 329 hybrid structures; 330,331 sheet piles; 118 and studs. 332 Besides, the influence of environmental conditions (such as water or elevated temperatures) on the shear characteristics of structures and joints was studied as well. 38,333,334 It is worth noting that particular attention has also been paid to web-flange junctions.…”

Currently, the application of pultruded profiles is increasing owing to their advantages, such as light weight, high strength, improved durability, corrosion resistance, ease of transportation, speed of assembly, and nonmagnetic/nonconductive characteristics. This review analyzes the main application fields of elements produced by pultrusion manufacturing processes: bridges and bridge decks, cooling towers, building elements and complete building systems, marine construction, transportation, and energy systems. Analysis of the scientific literature in relation to the mechanical behavior of pultruded elements is presented as well. Finally, this review outlines the future study possibilities, giving the researchers and practitioners the directions for deeper investigation of specific features and exploration of new ones concerning the mentioned aspects of pultruded fiber-reinforced polymer composites.

“…They performed 14 push-out tests with varying parameters, such as bolt strength, bolt diameter and bolt-embedding length. Similarly, Etim et al [ 17 ] developed several push-out tests to investigate the shear transmission between normal concrete and GFRP profiles. However, analytical methods have not yet been fully developed enough to precisely predict the shear capacity of the composite sections due to the complexity of the FRP–concrete connection.…”

Flexible Fiber Fabric for FRP–Concrete Connection of Thin Hybrid Slabs

2021

In order to combat corrosion issues, several studies on progressively replacing steel reinforcement elements with composite ones have been conducted in recent years. Hybrid steel–concrete thin slabs in which the steel acts as formwork are also candidates for update in the coming years. Achieving a reliable connection between fiber-reinforced polymer (FRP) and cast-in-place concrete is key to promoting this technology. This study analyzed different connection systems and proposes the novel approach of embedding a flexible fiber fabric as a superficially distributed connector between concrete and FRP. Eight specimens with four different connection strategies were tested using an experimental modal analysis and a quasi-static three-point bending test. The impact of the connection system on the vibrational response, flexural ultimate load, moment response, neutral axis position, shear and dissipated energy was obtained and compared. The results show that the use of an embedded mesh increases the frictional mechanism and produces the best performance in terms of load-bearing capacity and ductility.
