In beam-speak you say: this header must carry X-pounds per lineal foot. This translation is the key to any structural sizing problem. Armed with this information you can determine the minimum size, span or strength of the beam (credit julio). Engineered wood components are sized using span tables that match various spans to pounds per foot of beam. Raise The Trusses. Raise the trusses one at a time and work the ridge board into the gap. It will probably be a tight fit and take a little hammer work to get each one into place. Line the top of the truss with the top of the ridge board and nail the truss rafter to the ridgeboard on each side. Then nail the trusses into the top plate as normal.To get the same square footage, the correct max load per side of the hip is 9'/12.73' x 4.5'=3.184 ft at the ridge. 1/2 x 3.182' x 12.73' = 20.25 sq ft. That gives 3.182' x 2 sides = 6.36' in this case.

Instead of doubling the rise and run for the hip-rafter jig, multiply them by 1.5, which makes the jig easier to handle.

We need to calculate the total load per lineal foot (plf or pounds per linear foot) that the ridge beam needs to support in order to specify the correct size of the LVL. The span of the roof is ½ of the width, so 26'/2 = 13', and the length is ½ of the overall length since we will be using an intermediate post, so 36'/2 = 18':40ft x 12″ = 480″ (length in inches) ÷ 24″ on-center = 20 rafters. After getting the answer, add 1 for the ‘0’ rafter and multiply it by 2. You’ll get the number of rafters needed for your roof. 40ft x 12” = 480” ÷ 24” on-center = 20 rafters + 1 = 21 rafters per side x 2 = 42 rafters. Get a Free Roofing Estimate.The parallel support factor (k4) and the size factor (k24) from NZS3603 [2] are conservatively taken as 1.0.
