In a two – story building, an exterior column is to be designed for a service dead load of 1000 KN, maximum live load of 1500 KN, dead load moment of 60 KN m, and live load moment of 90 KN m. If the column dimensions will be restricted to 400 mm x 500 mm, fc’ = 27.6 MPa, and fy = 414 MPa, calculate the required column reinforcement.
Since, no information is given about the code, I have solve dthis question as per Indian Standards. I have attached image of SP 16:1980 (Indian Code - Design aids for reinforced concrete)
I have assumed cover d' = 50 mm
here, d'/D = 50/500 = 0.1 (Hence, I have used pg. 117 of SP 16:1980) (Please read the page carefully and understand the solution)
