Select one: Primarily used with conventional roofs Primarily used with truss roofs Primarily used with coupled roofs Primarily used with cut roofs Primarily used with pitched roofs List six major classes of foundation soil referred in AS 2870.1. Select one: a. A,S,M H,R & E b. A,S,M,H,E & P c. A,S,D,M,E & P d. B,A,S,H,E & P e.

Question 3 Correct Mark 1 out of 1 Question 4 Correct Mark 1 out of 1 Question 5 Correct Mark 1 out of 1 What type of load support system is pier and beam construction? Select one: a. This system of footing is basically a post and lintel method of load support. b. This system of footing is basically a series trench mesh connected with DN bars to provide a vertical means of support. c. This system of footing relies on good foundation material. d. This slab system fundamentally relies on steel reinforcement to hold it together to provide a lateral means of support. e. This system of footing basically the same as Pyramid construction. In highly reactive sites beams may require slip joints ( 2 layers of plastic membrane) why? Select one: to allow the soil to slip past the beam it allows the beam to rotate naturally to allow the beam to freely move against the soil allows the beam room to settle on the foundation material Why would you place compressible material under the beam in 'pier & beam' construction? Select one: AS 2870 suggests to use compressible material in all pier & beam situations. to accommodate ground heave to allow the ground to contract to accommodate ground sag to rid the site off unusable material that is inorganic in nature Footings quiz pass mark 80%: Attempt review https://learn.sydneytafe.edu.au/mod/quiz/review.php?attempt=132905... 2 of 10 3/7/2024, 9:25 PM

Question 10 Correct Mark 1 out of 1 Question 11 Correct Mark 1 out of 1 Question 12 Correct Mark 1 out of 1 In a strip footing what is the minimum cover where no vapour barrier is used? Select one: 20mm 40mm 25mm 50mm 30mm Steel reinforcement is placed in concrete to resist forces that are in: Select one: torsion compression tension strain bending What is the purpose of footings? Select one: Footings sizes are modified to suit the bearing capacity of foundation materials Footings are only needed on houses built on site classification "M" and above Footings are required to support the brickwork Footings transfer building loads to the foundation.
