A stockroom floor carries a uniform load of p = 80 lb / ft2 over half the floor as shown in Figure P12-12. The floor has opposite edges clamped and remaining edges and midspan simply supported. The dimensions are 10 ft by 20 ft. The floor thickness is 4 in. The floor is made of reinforced concrete with E = 3 × 106 psi and v = 0.25. Determine the maximum deflection and maximum principal stress in the floor.
