A community centre located in Ivanhoe, NSW, has a frame shown in Figure 3a. For design, the top chords can be considered to have intermediate restraints only about the major axis at mid-height. The connections at the ends of the top chords are through two (2) M16 bolts in 18mm diameter holes. The top chords have a cross-section of 190x45mm and are of seasoned hardwood grade F8. The top chords are 5m long. Analysis of the roof truss shows that the following unfactored axial compression loads are present in the top chord: a permanent load of 70kN and imposed action of 100kN considered as "loads of 5 months duration" due to the use of truss in crane activities. Note that short- term (s), long-term (₁) and combination factors (c) can be taken as zero. Determine if the top chords are suitable to support the applied loads considering that they support a tributary area of 20m². ✓ Figure 3a
