This would reduce deflection, but adversely affect horizontal stability as well as height.
WebDec 13, 2024 · We can merge these two equations to get a single rafter length formula based on roof pitch: rafter length² = (run × pitch)² + run². rafter length = √ ( (run × pitch)² + run²) rafter length = run × √ (pitch² + 1) If you're unsure about the terms such as roof run and rise, refer to the illustration below: WebFor a simple footway, a minimum clear width of 2.0 m is required by the highways authorities. Railway station footbridges can be less wide. To the sides of this footway, parapets are required, which should be 1.15 m high over roads or 1.5 m high over railways, the height measured from the footway surface in both cases.
WebRoof Truss Design. Architectural style, types of roofing material, methods of support of column framing, and relative economy are the principal factors influencing a choice among the three basic types of trusses: bowstring, pitched, and flat. In addition, side- and end-wall height and type, roof shape, and bracing requirements must be considered. WebFor loads around 10kPa (1.45psi) decrease the ratios by 10%. For car parks, decrease the loading by 10% (assuming car park live load of 2.5kPa or (0.36psi) Reinforcement cover assumed to be 20mm for slabs (0.8 inch) and 50mm for beams (1.97 inch). Adjust accordingly if larger cover is required.
