2. Design a square spread footing for the following conditions. Service dead load is 350 kips, service live load is 275 kips. Soil density is 130 lb/ftº. Allowable soil pressure is 4500 psf. Column is 18 in. square. Geotechnical analyses have determined the width to be 13 ft. fe' = 3500 psi normal weight concrete, and fy= 60 ksi. The base of the footing is placed 5 ft below the ground surface. Note: you don't need to design the bar...
Design a rectangular simple supported beam to carry service loads of 1.05 kips/ft of dead load (DL) (self-weight included) and 2.47kip/ft live load (LL) on a span length of 18 ft. The beam is limited to be (due to architectural reasons) 10” wide with an overall depth of 20”. Use f’c= 3,000 psi and fy= 40,000psi. Design the longitudinal reinforcement (flexure design) and the web reinforcement (Stirrups).
