RIDGE-TRUSSES—ANALYSIS FOR UNIFORM LOADS. 67 The web stresses for moving load are computed by taking the difference between thehorizontal components of the stresses in the chord members. Example.—Find the stresses in the truss of Fig. 107. Span = 80 ft.; ordinate 9a to the parabola (notto the chord… … Fig. 108. form of a parabola. The floor may be supported along the centre line 1-17, or may be hungbelow along the line AB. In the latter case the horizontal wind-truss in the plane ABprevents the swaying of the main truss longitudinally. With verticals and diagonals as in thefigure, the horizontal…
