Fall 2018 Week 4 Homework Quiz 12. Most concrete beams won't buckle laterally (sideways) unless what is present? 13. What kind of deflection calculations are required for concrete beams? 14. True or false: ACI permits the minimum depth table to replace deflection calculations for all beams. 15. The beam shown does not support construction likely to be damaged by large deflections. What is the minimum height of span BC in inches for deflection calculations to not be required? w = 2 kipsit 20" 333 16. What is the steel ratio p for the cross section shown? 15 in 3 No 9 18 in (4=3.0 in Din 12 in 17. The cross section in problem #16 is used as a beam with Grade 60 steel and pe=5 ksl. What is its coefficient of resistance Ro? 18. Is the beam in problem #17 strong enough to support a factored moment M. = 260 ft-k? Provide calculations to justify your answer. Name: CE 334- Week #4 Design of Rectangular Beams Homework Quiz 1. True or false: Use whole inches for the effective depth d of a beam. 2. What would be a reasonable estimate for d for the cross section shown? h=86. 3 #7 bars (upper layer) and 3 #9 bars (lower layer) b=18 3. What would be the minimum center to center spacing of the #7 bars for the cross section shown? Assume the maximum aggregate size is/d". 4. What would be the minimum clear spacing between the layer of #7 bars and the layer of #9 bars for the cross section shown? 5. A 4" thick floor slab is reinforced with #6 bars. What would be a reasonable estimate for its effective depth d? 6. What are stirrups used for? 8. What is the minimum width b that can be used for the beam in problem #7? The beam is not exposed to weather or in contact with the ground. 9. How would the minimum width b for the beam in problem #7 change if the beam were exposed to weather? 10. How do concrete cover and bar spacing affect the bar's development length? 11. When is "skin reinforcement" required? com/:w./t/personal/vlbrown_widener edu/_layouts/15/Doc.aspx?sourcedoc=%7B126bf527-0aff-47b6-87c0-b96677883 Fall 2018 Week 4 Homework Quiz Ace The beam shown has an overall height = 18".
