The current work investigates one of the most basic parameters affecting the stability of structural walls, which is (apart from the wall thickness) the degree of tensile strain of the longitudinal reinforcement of the boundary edges of load-bearing walls. The present work is experimental and in its framework, 5 test specimens of scale 1:3 simulating the boundary edges of structural walls were used. These specimens were reinforced with the same amount of reinforcement equal to a high longitudinal reinforcement ratio (3.68%). The degree of tensile strain applied was different for each specimen and it took values equal to 0‰, 10‰, 20‰, 30‰ and 50‰. The present research work tries to investigate the influence of the degree of tensile strain to the ultimate bearing capacity of walls using test specimens detailed with a high longitudinal reinforcement ratio.
