Maintenance & Repair Of Building Structure II - Quiz

Quiz Question

1. The foundation of a building or structure transfers the dead and live loads of the superstructure to soil that has enough bearing capacity to support the structure in a permanent, stable position.
True
False
2. Foundation walls without footing is usually is used for:
Light weight buildings
Bridges
Homes
Office buildings
3. Soil conditions may change over a period of time and introduce maintenance and repair problems even in initially well- designed foundations.
True
Fault
4. Which of the followings would be considered as common causes of foundation movement.
Settlement and differential settlement of the soil caused by inadequate compaction of the soil
Improper sizing of the footings
Over loading the structure
Excessive ground water which reduces the bearing capacity of soil
Inadequate soil cover which fails to protect against frost heaving
Adjacent excavation that allows unprotected bearing soil to shift from under foundations to the excavated area.
All of the above)
5. Localized foundation displacement may show upin:
Cracked walls
Damaged framings and connections
Sloping floors
Sticking doors
Leakage through a displaced roof
All of the above
6. The minimum practical thickness for a medium duty slab is:
4 inches
6 inches
8 inches
7. In the process called curing the concrete should be kept from drying out for at least
5 days
15 days
30 days
60 days
8. The structural component of a frame building should be strong enough and sufficiently rigid to transfer dead and live loads to the building foundations without excessive deflection or side sway.
Ture
False
9. Dead loads are those that result from the weight of the structure and live loads are those induced by external forces such as wind, earthquake, snow, inhabitants, furniture, equipment, or impact.
True
False
10. The fundamental principals of framing falls into two categories. Balloon frame and platform frame.
Ture
False
11. The balloon frame is light, economical, and simple to construct.
True
False
12. The balloon frame is more rigid and heavier than the platform frame.
True
False
13. Post and columns are vertical members which transmit loads directly to the foundations.
True
False
14. Post and columns below grade or in contact with earth must be treated with a preservative to resist decay and termite damage.
True
False
15. Beam or joists, which have failed in bending but have sound wood surrounding the failure, may be repaired by fastening adjacent pieces (scabs) to the side of the failed member.
True
False
16. There are many methods which can be used to reinforce girders, beams and joists. The selection of the proper methods should be determined by the loads to be carried, the costs, clearances, and accessibility.
True
False
17. Fire stops are obstructions deliberately placed in concealed air spaces to block passage of hot gases and flames from on area to another.
True
False
18. Failure of wall framing is usually related more to major structural faults elsewhere in the construction than to defects in the framing itself.
True
False
19. Warped studs can frequently be returned to original alignment with additional bridging. Headers, lintels, and sills can be returned to horizontal position by proper shimming.
True
False
20. Any major structural repairs or replacements such as the latter should not be undertaken in load bearing walls without first removing the loads from the wall under repair by adequate shoring and jacking.
True
False
