In this tutorial, we'll see how we can use Autodesk Robot Structural Analysis Professional to calculate the axial forces of the members of the truss. Sqrt (53) = 7.28 ' - this is the "rafter length" of your truss including the roof overhang. Note: multiply 0.28' x 12 (inches per foot) to convert back from decimal feet to feet and inches: your rafter length is 7' 3.4". Watch out: with a horizontal run of 7' and a rafter length of 7' 3.4" your roof is nearly flat. Based on your understanding of force balances guess whether a selected member of the truss is under compression under tension or is a zero member. Set the diagonal and vertical point loads with sliders. The reaction forces (blue) are calculated and displayed on the truss. Select guess force on a member use the popup menu select a member (from 1 to 13) and then select compression tensi;Calculators. Constructions. Roof Truss Calculator. Span: Pitch: Overhang: Quantity: Calculate Truss Area. Roof Truss Calculator: An Innovative Solution …Subtract the width of your floor joist from your floor's length: 120" − 1.5" = 118.5". Divide that difference by the sum of the on-center spacing of the floor joists: 118.5" / 16" = 7.40625. Add 1 to this value and round up the answer to the next whole number: 7.40625 + 1 = 8.40625 ≈ 9 floor joists.A truss tension and compression diagram is a graphical representation that shows the internal forces acting on the members of a truss structure.
