“…In the second stage, as the COD increases, the FPZ moves forward toward the loading point. According to the cohesive fracture model, it can be considered that the crack surface cannot transfer the tensile stress anymore, and a stress-free crack is formed when the COD is bigger than w c , Therefore, the length of the FPZ can be determined by the distance between the stress-free crack tip and the point where the normal stress reaches the ultimate tensile strength [9,30].…”

As a state-of-the-art method, the digital image correlation (DIC) technique is used to capture the fracture properties of wood along the longitudinal direction, such as the crack propagation, the strain field, and the fracture process zone (FPZ). Single-edge notched (SEN) specimens made of Douglas fir (Pseudotsuga menziesii) from Canada with different notch-to-depth ratios are tested by three-point-bending (3-p-b) experiment. The crack mouth opening displacements (CMOD) measured by the clip gauge and DIC technique agree well with each other, verifying the applicability of the DIC technique. Then, the quasi-brittle fracture process of wood is analyzed by combing the load-CMOD curve and the strain field in front of the preformed crack. Additionally, the equivalent elastic crack length is calculated using the linear superposition hypothesis. The comparison between the FPZ evolution and the equivalent elastic crack shows that specimens with higher notch-to-depth ratios have better cohesive effect and higher cracking resistance.

In the 1940's, potential of glass as a construction material was realized and improvement continued with the addition of zirconium dioxide in 1960's for harsh alkali conditions. To enhance durability of materials, new generation of glass fibres directed to improvement process. In this way, glass fibre reinforced concrete (GFRC) was started to produce for the satisfaction of different demands. Scientific studies and tests on the GFRC have shown that the physical and mechanical properties of the GFRC change depending on the quality of the materials and the accuracy of the production methods. GFRC can be used wherever a light, strong, fire resistant, weather resistant, attractive, impermeable material is needed. As technology advances, it is possibly expected to build the whole building and complex freeform with low cost. In recent years, the effect of glass fibres in hybrid mixtures has been investigated for high-performance concrete (HPC), an emerging technology termed, which has become popular in the construction industry.

“…The use of fiber reinforced polymer (FRP) composite has gained considerable interest and growing acceptance as internal [1][2][3][4][5][6][7][8][9][10][11][12] and external reinforcement [13][14][15][16][17][18][19][20] in concrete structures. FRP bars have a high strength-to-weight ratio but low elastic modulus and linear deformation until rupture, leading to brittle failure, larger deflections and crack widths compared with steel reinforced concrete structures.…”

“…FRP bars have a high strength-to-weight ratio but low elastic modulus and linear deformation until rupture, leading to brittle failure, larger deflections and crack widths compared with steel reinforced concrete structures. Therefore, serviceability limit state is generally controlling the design of FRP reinforced concrete structures [6][7][8][9][10][11][12] . Hybrid reinforced concrete structures [21][22][23][24][25][26][27][28] , where FRP reinforcement located closer to the external environment and steel bars embedded in concrete with largest possible cover, combine the advantage of ductility and durability of steel or FRP reinforced concrete structures.…”

This paper presents test results of fifteen reinforced engineered cementitious composite (ECC)-concrete beams. The main parameters investigated were the amount and type of reinforcement, and ECC thickness. All reinforced ECC-concrete composite beams tested were classified into four groups according to the amount and type of main longitudinal reinforcement used; three groups were reinforced with FRP, steel and hybrid FRP/steel bars, respectively, having similar tensile capacity, whereas the fourth group had a larger amount of only FRP reinforcement. In each group, four height replacement ratios of ECC to concrete were studied. The test results showed that the moment capacity and stiffness of concrete beams are improved and the crack width can be well controlled when a concrete layer in the tension zone is replaced with an ECC layer of the same thickness. However, the improvement level of ECC-concrete composite beams was controlled by the type and amount of reinforcement used. Based on the simplified constitutive relationships of materials and plane section assumption, three failure modes and their discriminate formulas are developed. Furthermore, simplified formulas for moment capacity calculations are proposed, predicting good agreement with experimental results.
