Normally, the ratio of ε^sub 1^/ε^sub 0^ should be less than 1.0 (ε^sub 1^ principal tensile strain is based on the tensile strength of concrete and is equal to approximately 0.33 , and ε^sub 0^ can be computed from the authors' Eq. (19)). (Eq. (19)) by considering only concrete strength and its limitation, but Yassin32 has suggested the following equation ε^sub 0^ = 0.002(1 + (ρ^sub s^ f^sub yh^/f'^sub c^)) (40) Please note that the aforementioned equation does include the effect of reinforcement in the reinforced concrete elements. Using these assumptions (Steps a through h) in the strutand- tie model concept, V^sub test^/V^sub n^ = 1.294 (mean value), a standard deviation of 0.151 and a coefficient of variation of 0.138 are found.
