3 1. The second floor of a light manufacturing building is constructed from a 4 thick stone concrete slab with an added 3 conder concrete fill as shown. If the suspended celing of the first floor consists of metal lath and gypsum plaster, determine the dead load for the design in pounds per square foot of floor area. 1 CE271 - Structural Analysis 1

4 2. The second floor of a light manufacturing building is constructed from a 5 -thick stone concrete slap with an added 4 conder concrete fill as shown. If the suspended ceiling of the first floor consists of metal lath and gypsum plaster, determine the dead load for a design in in pounds per square foot of the floor area.

5 3. A two story school has interior columns that are spaced 15ft apart in two perpendicular directions. If the loading on the flat roof is estimated to be 10 lb/ft 2, determine the reduced live load supported by a typlical interior column at (a) the ground-floor level, and (b) the second-floor level. CE271 - Structural Analysis 1 3

6 4. A four-story office building has interior columns that are spaced 30 ft apart in two perpendicular directions. If the flat-root loading is estimated to be 30 lb/ft 2, determine the reduced live load supported by a typical interior column located at ground level. CE271 - Structural Analysis 1 4

7 5. A hospital located in Chicago, Illinois, has a flat roof, where the ground snow load is 25 lb/ft 2. Determine the design snow load on the roof of the hospital. CE271 - Structural Analysis 1 5

8 6. The frame is used to support the wood deck in a residential dwelling. Sketch the loading that acts along members B and ABCD if I) b = 10 ft, a = 5 ft, II) b= 8 ft a = 8 ft, and III) if b = 15 ft, a = 8ft. Hint: See Table 1-4. CE271 - Structural Analysis 1 6

9 7. Classify each of the structures as statically determinate, statically indeterminate, or unstable. If indeterminate, specify the degree of indeterminacy. CE271 - Structural Analysis 1 7

10 8. Classify each of the structures as statically determinate, statically indeterminate, or unstable. If indeterminate, specify the degree of indeterminacy CE271 - Structural Analysis 1 8

11 9. Classify each of the structures as statically determinate, statically indeterminate, or unstable. If indeterminate, specify the degree of indeterminacy.. CE271 - Structural Analysis 1 9

12 10. Determine the reactions at the smooth support A and pin support B. The connection at C is fixed. CE271 - Structural Analysis 1 10

13 11. Determine the reactions at the supports A, C, and D. B is a hinge. CE271 - Structural Analysis 1 11

14 12. Determine the reactions at the supports A, C, and D. CE271 - Structural Analysis 1 12

15 13. Classify each of the following trusses as statically determinate, statically indeterminate, or unstable CE271 - Structural Analysis 1 13

16 14. Determine the force in each member of the truss and indicate whether it is in tension (T) or compression (C) using the method of joints. CE271 - Structural Analysis 1 14

17 15. Determine the force in each member of the truss and indicate whether it is in tension (T) or compression (C) using the method of joints CE271 - Structural Analysis 1 15

18 16. Determine the force in members JJ, DI, and DE of the Pratt truss and indicate whether it is in tension (T) or compression (C) using the method of joints CE271 - Structural Analysis 1 16

19 17. Determine the force in members KJ, NJ, and BC of the truss and indicate whether it is in tension (T) or compression (C) using the method of sections CE271 - Structural Analysis 1 17
