Determine the required splice length fоr the uncоаted lоngitudinаl bаrs in the following tied column made of normal-weight concrete. Assume that some of the longitudinal bars are in tension and that the connection should be designed as a Class B contact lap splice. Use ACI 318-14 Table 25.4.2.2 to calculate the development length, and assume that the ties satisfy the Code minimum.Column width, b = 22 in.Column thickness, h = 28 in.Clear cover to ties = 1.5 in.Number of longitudinal bars = 6Size of longitudinal bars = No. 6Size of ties = No. 4Concrete strength = 6,000 psiYield strength of longitudinal bars = 60,000 psiYield strength of ties = 40,000 psi
