In the figure, U-section steel purlins are used in the roof beam. Purlins are simply headstock and L = 4m has openness. Purlins are allowed for evenly distributed vertical load q = 1250N / m including dead load they are exposed. Since the slope of the roof is given as tan (Ī±) = 3/4; a) For the section in the middle of the span, calculate the normal stresses for the four corner points. b) What is the angle between the neutral axis and the x axis?
