AS1684 has four parts including Part 1 Design criteria; Part 2 Non-cyclonic areas; Part 3 Cyclonic areas; and Part 4 Simplified - non-cyclonic areas. This standard is the only framing standard adopted by the NCC/BCA as a deemedto-satisfy solution for structural timber framework. However, there are other standards for structural steel framework and brickwork together with commercially based timber engineered solutions, such as the Hyspan tables we will also use. Details (a) You are required to complete the following tasks utilising the appropriate AS1684 and Hyspan tables, floor plans and elevations, located on the vUWS web pages under Assignment 2. Requested drawing for Question 2 must be submitted on A3 paper, to suit scale requested. (b) Your project home is to be constructed in a non-cyclonic wind classification zone – category N2. Attempt each of the following questions: Question 1 - Wall and roof framing Using the tables from AS1684 and Hyspan, calculate the minimum size of the nominated timber members which will act as a uniform construction for the south-eastern elevation wall frame of your project home, all as detailed on the drawings which indicate a tiled, trussed roof @ 20½0 pitch. Assume all spacing at 450mm centres. Use only SEASONED timber as nominated and DO NOT use alternative sections as noted in Table A1. Common wall studs (notched) F8 Lintel to Family Room MGP10 Top and Bottom Plates (not trenched) MGP12 Lintel to form bulkhead beam Bed 3/Bath/Study Hyspan + Jamb studs to Laundry door F17 [Order length for above] Assume that we replace the trussed roof with a traditionally constructed 'coupled roof'. For the span across Section A-A and assuming that the roof is configured as detailed below, determine the minimum size of each of the roof members nominated, given that you must use SEASONED timber or Hyspan or Hyspan + as stated and that the studs are now spaced at 600mm centres. SECTION A-A Rafter MGP12 Underpurlin (continuous span with strut spacing @ 2.4m) Hyspan Continuous span ceiling joist (across Bed 1 with support to hanging beam @ max 2630 span) Hyspan + Hanging beam Hyspan Question 2 – Bracing On the A3 floor plan (i.e.at a scale of 1:100) show the Type A and/or Type B bracing distribution throughout the house based on wind direction towards south-eastern and north-eastern elevations. [Hint: in choosing your layout, make sure you comply with clause 8.3.2.3 and figure 8.4 in AS1684.4] Question 3 - Specific Fixings (Tie Downs) For this question ONLY, assume that the roof is a metal sheeted coupled roof. Nominate the specific fixings requirements from Table 9.6 for: 1. Bottom plate to slab 2. Continuous rafter to top plate with a rafter spacing @ 900mm and no ridge tie-down 3. Battens to rafters with batten spacing @ 1200mm
