Questions 11 - 15: Foundation Design (5 points each) Given the following column loading and footing information, determine the size of a mat foundation shown in Figure 2: Column Information: Column A: Live load = 50 kips, Dead load = 50 kips Column B: Live load = 60 kips, Dead load = 80 kips. Distance between two columns: 15 ft. Footing information: Distance from column A to edge of footing: 1 ft. Allowable soil bearing capacity (qall) = 3000 psf Weight of soil above footing = 120 psf Plain concrete unit weight = 160 pcf Depth of footing=2 ft.
Depth of soil above footing = 1 ft. 11. Name four shallow foundations. 12. What is the total column load? 13. Compute the effective soil bearing capacity (qeft) as (qall - soil pressure above the footing - concrete pressure by the footing on the soil). 14. Which of the following is the most likely length (L) of the footing? a) 14 ft. b) 16 ft. c) 18 ft. d) 20 f. 15. Which of the following is the most likely width (B) of the footing? a) 3 ft. b) 4 ft. c) 5ft. d) 7 ft.
