FRAMING
57. A homeowner has an issue with headroom going from a dining room to a living room due to a large dropped beam carrying roof loads. What is the best solution to solve this issue? A. Lift the dropped beam up into the trusses to make it a flush beam. B. Cut the existing roof off and use trusses in that area to reduce loading. C. Lift the dropped beam up into the ceiling joists to make it a flush beam. D. Cut the existing roof off and stick frame that area to decrease loading. 58. On an intersecting roof, what happens to the design length of the given rafters if the minor span is increased? A. Supporting valley rafter lengthens but the supported valley rafter remains the same because it is already supported. B. Supporting valley rafter stays the same because it remains attached to the major ridge at the same point. C. Both supporting valley rafters and supported valley rafters are lengthened. D. Supporting valley rafter remains the same, but it may or may not be attached to the major ridge at the same location. 59. On a 9 m (30') house span, trusses are designed for 10 m (34') to allow a small covering over the front entry. What is a likely cause if that roof begins to drastically sag at the front exterior wall? A. The trusses are simply deflecting normally as designed. B. The trusses were all installed backwards and the bearing supports are 1.3 m (4') from the back wall. C. The exterior front wall has shrunk due to drying of plates. D. The front exterior wall must be bowing outward because the trusses cannot deflect like that at the heels. 60. In a dimension lumber floor system, cross bridging is one way of dealing with joist restraint. When should the bottoms of the cross bridging be fastened? A. Immediately while building floor so the floor is complete before sheathing. B. Once floor sheathing is complete because now joists have been nailed straight. C. Before the subtrades come in so they can not knock them out as easily. D. Just prior to drywalling so floor has had time to straighten and settle. 61. Diagonal top chord braces are critical to prevent the top chords from buckling underforces such as wind. How else can this be done so the braces do not have to be removed when sheathing the roof? A. Run the diagonal top chord braces on the underside of the top chords. B. Diagonal web bracing at each gable end running in both directions (an “X”). C. Run diagonal web braces at each gable end from top of gable and angled back to the fourth or fifth bottom chord. D. Run all the truss top chord lateral braces on the underside of the top chord. 62. What must be done to a dimensional lumber floor system to stiffen the joists? A. Install continuous stiffeners to all joists at 600 mm (2') o/c. B. Install vertical stiffeners to all joists at 600 mm (2") o/c. C. Install 2x4 blocks between joists at1800 mm (6') o/c max. D. Install cross-bridging between joists at 2100 mm (7') o/c max. 63. How should web stiffeners be installed where an I joist bears on an interior load bearing partition? A. With a ¼" gap at both chords. B. Tightly between top and bottom chord. C. With a ¼" gap at the top chord and tight to the bottom chord. D. Tight to the top chord with a ¼" gap at the bottom chord. 64. A water closet is located on an interior wall and the soil pipe must pass thru three I joists to reach the stack what procedure is used? A. Notch the top chord of the joist. B. Notch the bottom chord of the joist. C. Drill holes as far from the bearing wall as possible. D. Drill the holes as close to the bearing wall as possible. 65. In balloon framing what procedure is used to install the second floor, floor joist? A. Nail blocking between studs at under side of joist and nail joist to stud. B. Let in continuous 1x4 ledger at under side of joist and nail joist to stud. C. Nail joist to stud with six 3½" coated nails and 2 lag bolts. D. Nail joist to stud and set a cripple under each joist. 66. Using the following specification, what is the rough opening for the exterior door? Door size 8 500 mm x 2 012 mm (31¾" x 79¼"). Jamb size 28 mm (1-1/8"). Rabbit depth 12 mm (½"). Threshold 32 mm (1¼"). Allow 12 mm (½") clearance around including under threshold. Metric A. 856 mm x 2084 mm B. 860 mm x 2182 mm C. 860 mm x 2200 mm D. 890 mm x 2190 mm Imperial A. 34" x 82¼" B. 33¾" x 82" C. 33" x 82¾" D. 35¼" x 82½" |
