BCT 122 Roof Framing 1 ROOF FRAMING PLANS ARCHITECTURAL ROOF STYLE IDENTIFICATION ROOF FRAMING MATERIAL CALCULATIONS FROM PLANS. Roof Design • Roof design is a major feature of a house’s architectural style. • The plan reader should be familiar with roof styles and the rafter components of these designs to calculate roof framing materials and framing labor . • Example: Would the framing labor and material for a steep pitch Victorian roof be the similar to a Colonial roof house, both
Roof Framing Calculations Common Rafter Unit Line Length The unit LL run for all common rafters is 12 inches. The unit rise will be also be expressed in inches. The unit line length is the hypotenuse of the run and rise. Formula: run² + rise² = hypotenuse². Sq root = unit LL. Unit LL divided by 12 = unit LL factor. Download full-text PDF. Optimum Design of Pitched Roof Steel Frames with haunched Rafters by genetic algorithm . Conference Paper (PDF Available) · September 2001 with 2,967 Reads How we measure Wood Framing Rafter+ lets you quickly create full rafter systems in Revit® models for timber frame roofs of any shape or complexity. Custom-framing functions and versatile schedule generation further accelerate BIM workflow. No more drafting – you just design and decide. Our roof rafter calculator tools are handy for calculating the number of rafters needed, rafter length calculator, lineal feet of rafter, board feed in ridge and sub-facia,and the total board feet in the roof. Rise and Run means that a 6/12 pitch roof has 6" of rise (vertical) for each foot of run (horizontal). Structural Design for Residential Construction Cynthia Chabot, P.E. Chabot Engineering www.chabotengineering.com. What is residential construction? • One and two family dwellings • Typically wood framed construction in this part of the world . What does a structural engineer typically do? Drawing by Americad • Analyze load paths to ensure they go down to a foundation • Connections – connections – connections • Roof, floor, and wall assemblies • Beams, columns, headers Chapter 3 DESIGN CONCEPT FOR PRECAST SYSTEM 3.1 STRUCTURAL CONCEPT Based on considerations of buildability, economy and standardisation of precast components, the structural concept developed consists of: • Conventional foundations comprising footings, raft slab or piles and pile caps. 2×4 rafter (A) measures 6′ 7 1/4″ with 30 degree miter cuts on both ends, same direction (see illustration above). 2×4 rafter (B) measures 10′ with 60 degree miter cuts on both ends, opposite directions (see illustration above). Assemble the rafters as shown above. Cut the 1/2″x8”x14″ plywood gussets to size and nail to the

ROOF FRAMING In this chapter, we will introduce you to the fundamentals of roof design and construction. But, before discussing roof framing, we will first review some basic terms and definitions used in roof construction; we will then discuss the framing square and learn how it’s used to solve some basic construction problems. Next, we’ll examine various types of roofs and rafters, and techniques for laying out, cutting, and erecting rafters. We conclude the chapter with a discussion of Rafter calculator dimension diagram Open page with full scale printable birds-mouth cutting template at current rafter angle and dimensions. Remember to allow for Ridge Thickness in Rafter Run to Outer Wall. Roof layout requires a number of steps; laying out and cutting rafters is one. There are a number of methods to accomplish marking and cutting out rafters. I will attempt to describe the method I find that works the best for me. Rafter Layout RAFTERS are framing members that support a roof. They do for the roof what joists do for the floor and what the studs do for the wall. They are generally inclined members spaced from 16 to 48 in, apart that vary in size, depending on their length and the distance they are spaced. IRWIN® Rafter Square can also be used as a Protractor, Saw Guide, and Tri & Miter Square L’équerre de charpente IRWIN® peut également être utilisée comme rapporteur d’angle, guide de scie et équerre à épaulement et à onglet
