A nonslender square corner column is subjected to biaxial bending about its x and y axises. It suppoerts a factored load Pu= 300,000 lbs acting at eccentricities ex=ey= 7 in. Design the column size and reinforcement needed to resist the applied stresses. Given: f'c = 4000 psi fy = 60,000 psi. d'=2.5 in. Gross reinforcement percentage, px=0.03. Solve by using all three methods.
Please show all work and explain your steps, please.
