Determine the required splice length for the uncoated longitudinal bars in the following tied column made of lightweight 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 = 26 in.Column thickness, h = 16 in.Clear cover to ties = 1.5 in.Number of longitudinal bars = 6Size of longitudinal bars = No. 7Size of ties = No. 4Concrete strength = 7,000 psiYield strength of longitudinal bars = 60,000 psiYield strength of ties = 40,000 psi
