Analytical method for the assessment of unreinforced brick masonry walls subjected to eccentric compressive loads

Abstract: Slender unreinforced masonry walls are likely to fail due to mechanism formation when they are subjected to eccentric compression loads causing second order bending effects. A practical analytical formulation is herein presented to provide an accurate calculation tool for these cases. The proposed method is compared with Eurocode-6, ACI-530, Southwell Plot method (semi empiric), a Finite Element Analysis and experimental tests. The results show that the proposed method and ACI-530 are accurate at calculating t… Show more

“…13), the total eccentricity, e, which takes into account the initial eccentricity, e 0 , and the second order deflection of the wall at mid-height. This formulation, which is derived from the classical buckling theory of elastic beams, has been used in previous researches and documents [33,43,44]. The Young's modulus of the masonry used in this equation is updated at each step according with (Eq.…”

“…Rehabilitation comprises repair, strengthening and seismic retrofit, and many researchers still study it because of the exceptional advantages that FRP composites offer compared to the traditional strengthening methods [4][5][6]. Nevertheless, in recent years, researchers have also proposed to form new structures entirely from FRP, or hybrid new structures from combining FRP with other materials, including concrete, metal or timber.…”

“…The B500S bars were characterized by the mechanical properties indicated in Table 5. 4, where 𝑓 𝑦 represents the yield strength, 𝑓 𝑢 the maximum sustainable stress, 𝐸 𝑠 the modulus of elasticity, and 𝐸 𝑠,ℎ the elastic modulus of the hardening branch. The second elastic modulus was estimated as 0.005𝐸 𝑠 , as suggested by the study of Nie et al [134].…”
