“…According to sandwich theory, the shearing force of FRP/AAC panel is, V=V c +V frp +V s (1) Where V c , V frp , Vs are the shear provided by concrete, FRP, and steel reinforcement, respectively. Proposed by Chen & Teng, [5] V frp =2 V frp, e t frp w frp [h frp,e (sinβ+cosβ)]/s frp (2) f frp,e is average stress in crossing area of FRP and shearing crack, t frp is the thickness of FRP, w frp is the width of FRP stripe, s frp is the FRP stripes' spacing, β is the horizontal angle of FRP fiber, h frp,e is effective height of FRP stripes.…”

Abstract. The structural behavior of fiber-reinforced polymer (FRP) reinforced autoclaved aerated concrete (AAC) panels has been investigated. Four FRP/AAC panels and two non FRP AAC panels were prepared for testing. The panels were tested under four-point bending test to investigate their strength and displacement of mid-span responses using a bending pressure testing machine. Experimental results showed that FRP laminates increased the bearing capacity of AAC panels. A theoretical analysis was conducted to predict the strength of the FRP/AAC member, and the results found were in good accordance with the experimental results.

The Application of Carbon Composites in the Rehabilitation of Historic Baroque Vaults

Abstract:The stabilization and reinforcement of damaged barrel vaults with lunettes over an arcaded walk, applying composite strips based on high-strength carbon fibers and epoxy resin, was performed during the restoration of a historic monastery. The application of reinforcing composite strips in the soffit of damaged barrel vaults was preceded by relatively extensive experimental research and theoretical analyses. This method significantly reduces the interventions into and the degradation of the original historic structure (surface application) and is reversible.

“…Therefore, the inorganic cementitious materials were applied to replace the epoxy resin so as to develop the relatively new strengthening techniques, e.g., the FRIP (fiber-reinforced inorganic polymer) Ding et al 2014), TRM (textile reinforced mortars) (Al-Salloum et al 2012;D Ambrisi et al 2012;Chalioris et al 2014;Larrinaga et al 2014;D'Ambrisi et al 2015;Escrig et al 2015) and cement based dry fiber sheets (Hashemi.

As the fibre reinforced polymer (FRP) sheets/textiles strengthening the inorganic cementitious materials technique was presented by some researchers, a few of potential shortcomings, such as penetrating difficultly of cementitious materials to and much brittle of FRP sheets, have been found in recent years. Therefore, a new strengthening system, which was FRP grid strengthening ECC system, in combination with the Engineered Cementitious Composites (ECC) and FRP grid was proposed by the present authors. By applying this system to reinforce the reinforced concrete (RC) beams, the dual strengthening effects can be provided and the intermediate crack-induced debonding failure can also be suppressed by externally bonded the FRP gird reinforced ECC composite layer to the tensile surface of the original RC beams. To investigate the tensile mechanical behaviour of FRP gird reinforced ECC composite layer, six non-strengthened ECC specimens and eighteen basalt fibre reinforced polymer grid (BFRP) strengthening ECC composite specimens (FRP-ECC specimens) subjected to the unidirectional axial tensile loading were conducted in this paper. Three kinds of different thickness BFRP grid were applied to investigate their reinforcement effects. The test results showed that there was no slip at the interface of BFRP grid and ECC substrate significantly. The failure modes were the internal PVA fibers ruptured or pulled out from ECC substrate for the non-strengthened ECC specimens and the rupture of BFRP reinforcements of grid for the strengthened FRP-ECC specimens. The axial stiffness of FRP-ECC specimens and the ultimate tensile stress and strain were obviously increased after the ECC substrate cracked, which indicated the contribution of the internal BFRP grid reinforcements. Moreover, an analytical model was also presented to predict the stress-strain relationship and the tensile strength of the FRP-ECC specimens and validated through comparison with the rest results.
