Diagonal tensile tests on historical brick masonry wallets strengthened with fabric reinforced cementitious mortar

Shear behavior of hollow clay brick masonry wallet coated with short jute fiber reinforced mortar

“…After reaching the maximum load, the mechanical behavior of walls reinforced with fibers is characterized by a gradual loss of load-bearing capacity and the simultaneous formation of various failure mechanisms, as shown in Figure 14. In addition to coating cracking, detachment between the coating and the ceramic blocks was observed, as reported by Mezrea et al (72), and the rupture of the ceramic block. The There was also a tendency for fiber pullout in these regions (Figure 15c); d) Crushing of the bricks (Figure 15d).…”

“…The unreinforced walls, under diagonal compression test, presented vertical cracking from the point of load application, which is common for this type of test, as shown in Figure 13. This shear failure mode, already identified by other authors (72,13), occurs when the principal tensile stress developed internally in the wall exceeds the tensile strength of the masonry components, including the coating (73). Figure 14 depicts the failure mode of walls reinforced with short jute fibers, identified as toe crushing, which is a result of wall crushing under compression (toe compression failure).…”

Active Confinement of Masonry Walls with Stainless Steel Straps: The Effect of Strap Arrangement on the in-Plane Behavior of Strength, Poisson’s Ratio, and Pseudo-Ductility

“…where n-the coefficient between 0 and 1, relating to the rate of voids in the specimen, with n = 1 in the absence of voids (Appendix A)-takes the value 0.97, as in Reference [62] (for the meaning of w, h, and t see Section 2). It is worth noting that the tensioned straps compress the mid-plane of the masonry wall along the edges of the specimen but not at its center of gravity [11], where the additional compressive stresses are perpendicular to the mid-plane (Figure 1).…”

Behaviour and material properties of versaloc semi-interlocking mortarless masonry

“…This repeatedly observed failure pattern can be considered as governing the in-plane behaviour for wallet aspect (height-to-length) ratios less than 1. For this reason, the standard interpretation of the diagonal tension test results as presented in the literature [22][23][24][25][26][27] is not applicable to these wallets. The compressive strength given in Eq.…”

“…Therefore, the tensile strength of masonry unit, f tu , is generally assumed to be 10% of the compressive strength of the units in the Finite Element (FE) models in the recent studies of Shi et al [19], Zahra [20] and Martı ´nez et al [21]. One of the techniques to measure the tensile strength of mortared masonry composite is to conduct diagonal tension test, which entails subjecting masonry wallets to diagonally compressive loads [22][23][24][25][26][27]. As the joints in ungrouted mortarless masonry are dry and susceptible to in-plane sliding, the feasibility of conducting diagonal tension test on this type of construction was studied in the present investigation.…”
