Marks: 1 mark per question 1. Which of the following regarding tension and compression is/are TRUE? A B C Tension is the squeezing force placed on a material Steel is equally strong under tension and compression. Concrete performs better under compression than tension. Adding steel to a concrete beam may improve the beam's tension capacity, but not its compression capacity D (1) A and D only (2) B and C only (3) A, C, and D only All of the above 2. A building frame that has studs lined continuously from the first floor joists to the top plate of the second floor, with each of the studs placed 30-60 cm apart, and rests on the sill plate that is secured to the foundation is a: (1) platform frame (2) plank wall frame. (3) balloon frame. (4) stud frame. 3. Which of the following is a drawback to flat sawn lumber? (1) (2) (3) (4) It tends to expand over time It rots much quicker than quartersawn It tends to shrink and bend into a cup shape over time It is unattractive looking 4. Which of the following statements regarding soil characteristics is FALSE (1) Bearing capacity is the capacity of a soil to resist applied loads without excessive settlement. (2) Consolidation is the deformation of soils undergoing compression and settlement. (3) Shear strength is the resistance to lateral deformation, and is dependent on cohesion and friction Cohesion is a measure of the case with which individual soil particles can be forced to slide past each other. - Assignment continues on the next page - 5. Which of the following statements regarding roof structure is FALSE? (1) (2) (3) A roof sloped 12/16 is less steep than a roof sloped 16/12. A roof sloped 6/10 is more steep than a roof sloped 6/12. Rafters and ceiling joists are common in homes built prior to the 1960s, while prefabricated trusses are common in more recent home construction. Ratters and ceiling joists are prefabricated and are structurally more efficient than trusses. 6. A processed wood product that is produced by laminating thin sheets of soft wood and laid down in alternating patterns of 90 degrees is called: (1) particle board. (2) waferboard (3) plywood (4) oriented strand board. 7. A truss is: (1) (2) (3) (4) a solid or built-up post under beam or point load the supporting structure over an interior opening. an engineered, prefabricated roof or floor support structure. the horizontal lumber that the studs rest on at the bottom and the top of all framed walls. 8. Which of the following statements is/are FALSE? A. . C D. Spread footing distributes the weight of structural loads from the grade beam until the weight per square unit of footing is greater than the bearing capacity of the soil. Piers extend below the frost line. When using piles, loads are transferred by friction to the soil along the pile's length. The height of the crawl space must be less than 6. (1) (2) (3) (4) A only B and D only A, C, and D only All of the above 9. Which of the following materials is best suited for subfloor applications? (1) Aspenite (2) Particle board (3) Parallam (4) Fibre board - Assignment continues on the nextpage- 10 How may windows be incorporated into a structure? A . B . C D. Adding a header above the opening where the adjacent studs have been doubled or tripled Placed between the posts in a post and beam framed structure The lumber is doubled or tripled beside the opening creating edges and double joists. Included in prefabricated walls and joined with other components on site. (1) (2) (3) (4) A and only Band C only A. B. and D only All of the above 11. Platform framing A . consists of studs that rise continuously from the first floor joisss to the top plate on the second floor involves floor joists, headers and subfloor scathing constructed over the exterior foundation walls and main beams. is primarily used in contemporary construction is similar to balloon framing, with the only difference that the stads only extend one storey and are capped by a top plate C. D. (1) (2) (3) (4) A and B only C and D only A and Donly B and C only 12 Consider a building with a static foundation. The building is currently under renovation. Which of the following statements is/are TRUE! A B. C D The bearing capacity of the soil underneath the building is typically equal to or above 5.000 kilograms per square metre. The shear strength of the soil is equal to its bearing capacity The soil has completed the process of consolidation The downward force of the building foundation is in equilibrium with the soil's allowable bearing capacity (1) (2) (3) (4) A and B only A and D only B, C, and D only A.C. and D only 13. A rafter is: (1) (2) (3) the structural member that supports the ceiling finish the structural member that supports the roof deck. an engineered. prefabricated roof or floor support structure the supporting structure over an exterior opening 14 A ceiling joist is: (1) the structural member that supports the ceiling finish (2) the structural member that supports the roof deck (3) an engineered, prefabricated roof support structure. the supporting structure over an exterior opening. 15. Which of the following concrete admixtures best mitigates problems associated with a short curing time of the surface layer caused by extreme heat? (1) Air-entraining agents (2) Aggregate (3) Retarding agents Accelerators Questions 16-20 are based on the video series, Part 2: Framing and Weatherproofing. Completion of this assignment requires you to identity and answer all the questions. The video series is found on the Online Readings webpage - Pre-Reading Reference 16. What is the purpose of the rolls of blue Styrofoam in the picture below? (1) Helps seal out insects (2) Acts as the joint sill plate gasket (3) Reduces heating and cooling energy loss All of the above 17 What is the name of the framing element indicated by the sumber "I" in this picture? (1) Lintel (2) Joist (3) Sill (4) Stud 18. What style of roof is pictured here? (1) Hip tool (2) Mansard roof (3) Gable roof (4) Gambel roof to come 19. What is the purpose of the red chalk line on the top of the concrete foundation wall? 4 (1) Defines edge for floor sill to the left and base for first brick course on the right (2) Verily alignment of the foundation wall (3) Defines center placement for floor joists (4) Indicates areas to be cut out for basement windows 2(), What is the advantage of using a floor sill plate that is four layers thick, versus one layer?
