While designing the roof truss as a whole, the purlins are failing in output results on analysis. For example, as much as possible purlins should be placed at joints of truss (as shown in the left side of the figure 5) so as not to induce secondary bending and shear forces in the members of the truss. Verify the beam for bending.
