Design a flat roof truss of a car park building as shown in the figure below. - Height of truss is $5.5\mathrm{m}$ rise and a width of $20\mathrm{m}$. - Assume the truss is simply supported. - The sections used for truss is angles and channels only. - The load is uniformly distributed along the top. - Any missing data may be suitably assumed. Figure 1: Flat truss. Design should be as per BS code specifications. 1. Determine the loads applied to the top joints. [ 2 marks] The dead load on top should be taken as $70.\mathrm{KN}/\mathrm{R}$, and live load must be taken from $\mathrm{BS}$ reference. 2. Analyse the truss using an appropriate method to find the internal forces. [5 marks] 3. Design one tension member in a truss. [4 marks] 4. Design one compression member in a truss. [4 marks]
