SSD4701 ASSESSMENT 2 2022 Section B: Structural Design of Steel [30 Marks) 1. For the roof frame below (assuming that the frames are regularly spaced at 5 m intervals) determine all possible sheeting (IBR686) for the roof for: 05 purlins as single or double/multiple span () 6 purlins as single or double/multiple span [10] Purlins frames 7,sm 7,sm 5m t 2. Assuming the following information is given for the roof above. [20] - 5 purlins per roof side - The purlins are arranged as 4 span purlins - The roof is considered accessible. - Wind uplift: 0.3 kPa - The total load of the insulation on the roof is 0.5 kN/m2 Determine the design load for a cold-formed lipped channel 250 X 75 X 20 X 4.5 purlin. The purlin has the following properties: Modulus of elasticity E = 210 GPa Yield stress fy = 300MPa [. Lipped Channel
