Truss installation. roof trusses are pre engineered to precise specifications & dimensions per the architectural plans. they are designed to handle code minimum design forces under the most extreme conditions. we pick up the story with the trusses installed & the roof sheathing (plywood) under construction. This video explains in detail how to build a hip roof.
1. attach 4 6 centering rafters and lift the ridge beam into place. the first step in the process of erecting the hip roof is to get the ridge beam into place at the top of the roof. place the 4 6 common rafters in their designated positions along the 2 longest walls, and nail them firmly to the wall with a nail gun. B. triangle truss configurations. below is a detailed breakdown and, in most cases, an explanation of each type of truss. 1. studio two bearing points truss. 2. studio three bearing points. used on larger trusses and for creating a pitched ceiling or an extra vertical space. 3. coffer tray truss. Hip roof designs. hip roofs can be designed over square shaped buildings, as well as on rectangular ones; the design of hip roofs can follow triangular sides, as well as a combination of triangular and trapezoidal sides. some hip roof designs follow pyramid shapes, whereas others may have more symmetrical structures. If your roof has a long slope on one of the shed’s side, one of your rafters should be longer. so, know the number of the roof trusses you’ll need, then double the number for you to acquire the number of the rafters you’ll need when building the roof trusses. step #2. cut the rafters from 2×4 piece of wood.

Make this layout jig and cutting guide from a piece of plywood that has a square factory corner. for the common rafter jig, just double the roof pitch in inches. for a 6 in 12 roof, mark 12 in. on one side for the rise and 24 in. on. the other edge for the run. connect the marks to complete the triangle. Roof truss design. using the skyciv s3d, we can analyze the roof truss: . we will assume that the roof truss is simply supported and will be analyzed in 2d by adding supports on each node with code rrfrrr to only fix the z axis displacement. the initial section we will be using is an aisc l shape – 2.5”x2.5”x3 16”.
