Channel sections are used as a purlin. The top chords of the truss are sloped at 5H to 2V. Trusses are spaced 5m on centers and the purlins are spaced 1.4m on centers. Use the properties of the channel section BELOW. Loads: (Consider all loads pass thru the centroid of the section.) Dead load = 750 Pa Live load = 1,000 Pa Wind load = 1,400Pa Wind coefficients: Windward = 0.3 Leeward = -0.5 Use Fbx=Fby=250 MPa. Determine the maximum value of the interaction equation using the load combination of 0.75(D+L+W)
