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.The Warren truss has equal length compression and tension web members, and fewer members than a Pratt truss. A modified Warren truss may be adopted where additional members are introduced to provide a node at (for example) purlin locations. Warren trusses are commonly used in long span buildings ranging from 20 to 100 m in span.The degree of indeterminacy for trusses is given by the following equation: ie = m + r − 2j (8) (8) i e = m + r − 2 j. Note that these equations do not necessarily tell the whole story because a truss can still be unstable due to an internal collapse mechanism as will be described in the next section. If you try to solve for the internal ... Right-click a member to delete it. Add Support: Click on nodes to toggle the type of support.
