1. The problem statement, all variables and given/known data A 24in diameter concrete column, at tenth story of an office building, is supporting the flat roof slab is subjected to a wind uplift load of 50.00kips while carrying a factored compressive force of 120.0kips. the column is 10.00ft long. Assume elasticity of concrete to be 4200ksi and the ultimate compressive and ultimate tensile strength as 2.400kis and 0.2000ksi respectively. Determine: Diameter: 24 in Wind uplift load: 50 kips Compressive force: 120 kips Colums length: 10 ft Concrete elasticity: 4200 ksi Area (A): 452.39 in^2 2. Relevant equations a) The axial compressive stress from compressive force only b) The axial tensile stress from wind action only c) The net stress d) The deformation of the column e) The strain in the column f) The factor of safety? Is the column safe? Check whether the roof is carried away or not? 3. The attempt at a solution A = 0.2653 ksi B = 0.1105 ksi C = 0.1547 ksi Sorry, but I am not sure if my answers are correct. Also I don't know how to solve d, e, and f. Thanks in advance.
