Calculate trusses.

Starting at one end of the roof, mark the first truss flush with the outside edge of a cap plate. Use a level, square, and measuring tape. Hammer a nail in place to hook your measuring tape and space out the subsequent trusses every 2 feet or other designated spacing. Measure out 5 to 6 trusses at a time. Mark the landing point of the truss ...How to Calculate the Length of a Rafter. A rafter is a structural member that provides support for the roof sheathing and transfers the weight of the roof to the exterior walls of a building. Calculating the length of the rafters is an essential part of framing a roof.. There are many different types of rafters, and the type you use will be influenced by the type of roof.Calculate Truss Load. The formula for truss loads states that the number of truss members plus three must equal twice the number of nodes. If the number of members is labeled M and the number of nodes is labeled N, this can be written as M+3=2*N. Both sides of the equation should be equal in order to end up with a stable and secure roof structure.

Trusses typically follow a pretty general and common structure, made up of various components. Below is a list of the relevant parts of a truss: (1) Top Chord – the beam of a truss spanning the length of the truss. (2) Bottom Chord – the bottom beam spanning the length of the truss. (3) Web – these are the internal members of a truss.

Suppose the base of the actual roof is measured to be 40 feet. You can set up the following equivalence: base of triangle/base of actual roof = hypotenuse of triangle/hypotenuse of roof. Plugging in the numbers, you get 1/40 = 1.06 /x, where x is the required rafter length. Solving for x, you get x = (40) ( 1.06) = 42.4 feet.Input the roof length, the on-center spacing (the distance between the middles of two neighboring roof trusses), and the roof truss calculator will return the number of roof trusses needed.
