The building frame shown below has a single 40 ft long continuous beam A-B. The beam experiences an evenly distributed dead load of 1.0 kip/ft (including self-weight). Columns are evenly spaced at 10 ft intervals (column 1 at 10 ft from support A, column 2 at centerline, and column 3 at 10 ft from support B). Roof loading can be simplified as point loads at each column where column 1 and column 3 are 75 kips and column 2 is 110 kips. Side walls are 24 inches thick. Given the beam cross section with #10 longitudinal bars and #4 Stirrup Bars Find: A. The spacing required for the #4 stirrup bars with 2 legs (use a single spacing throughout the beam). If not adequate would 3 legs work? Will 4? B. Show if it is possible to cutoff two of the #10 longitudinal bars, and the location of the cutoffs if it is possible. C. Find the development length of the #10 stirrup bars and show if it is necessary to include hooks. 110 Kips 75 kips 75 kips 10.0000 -10.0000 ft 10.0000 ft -10.0000 ft ft AI B B 24" 24" 18.0000 4-#10 Grade 60, non-epoxy, longitudinal bars #4 Grade 60 stirrup bars 23.6750 1.5 inch clear cover around stirrups f'c= 4000 PSI 3.7500 2-4000 2:4000 12.3250 Annotations on beam cross section shown are in inches. 2:8500 The building frame shown below has a single 40 ft long continuous beam A-B.
