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.Students take a close look at truss structures, the geometric shapes that compose them, and the many variations seen in bridge designs in use every day.

Step #2. Cut the rafters from 2×4 piece of wood. Cut it to the length you require and add the plumb cut to its ends. Here's a step-by-step overview of the design process for timber roof trusses: 1. Preliminary Design: In this step, the designer is to determine the roof span, pitch, and overall architectural design of the building. It is important to choose a truss configuration based on structural performance, aesthetic preferences, functional requirements ...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.
