Problem 5 The cross section of a short axially loaded tied column shown below is reinforced with 8020 steel bars, the concrete compressive strength f' = 28 MPa, and yield strength of steel is fy = 420 MPa, calculate the following: Assume the clear cover is 40 mm. 400 mm Ø10@200 mm 8020 Required Answer Unit The provided reinforcement ratio (Pg) Does the reinforcement ratio satisfy the ACI code requirements? (Yes/No), why? The clear distance between steel bars (Sc) Does the clear distance between steel bars satisfy the ACI code requirements? (Yes/No), why? Does the provided spacing between ties satisfy the ACI code requirements? (Yes/No), why? The design load capacity (Pn) 400 mm
Expert Answer
Solution. Does the provided reinforcement ratio satisfy the ACI standards? Yes. The provided reinforcement ratio satisfies the ACI 318-19 standard for the minimum and maximum reinforcement requirement for a non-prestressed column. As per section 10.6
