26 points Save Answer QUESTION 13 A hospital is to be built in Bourke, NSW. Figure 2a shows the timber frame of the hospital. The diagonals in the main truss are 4m long, have a cross-section of 240x35mm and are seasoned softwood of grade F14. The connection at the ends of the diagonals is through three (3) M10 bolts in 12mm diameter holes. The 3 bolts at each end are located at a cross-section perpendicular to the longitudinal axis of the diagonals. Structural analysis of the frame, using structural engineering software, shows that the following unfactored axial tensile loads are present in the critical diagonals: a permanent load of 20kN and an imposed action due to people of 30kN considered as "loads of 5 months duration" due to frequent use of the roof area for storage. It can be assumed that short-term (s), long-term (₁) and combination factors (c) are equal to zero. Determine if the diagonals are suitable to carry the applied loads (22 Marks). The factor k6 is one of the factors required in timber design. Briefly explain its importance in relation to timber construction in different locations around Australia. List one industrial application where k6 may need to be applied regardless of the location of the timber structure (4 Marks). Figure 2a
