A plain concrete column 14 in. x 14 in. x 10 ft high is subjected to an average stress of 1,000 psi. Compute column shortening in 5 years if the load is applied 2 weeks (14 days) after the concrete is cast. The concrete is 3,500 psi NWC (145 lb/ft3 ), made from Type I cement, and was moist-cured for 5 days. The average relative humidity is 50 percent. Use the ACI 209R method. Assume top and bottom of column are not exposed to the atmosphere.
