(Planed All Round) category. Divide the maximum load of one joist by the area supported by one joist: 462 kg (1,019 lb) / 1.72 square metres (18.7 sq feet) = 269 kg per square metre (54.5 lb per square foot). The d is the depth of the joist in inches, which you will have to measure. If the example floor is 6 by 9 metres (20 by 30 feet), the total area is 54 square metres (600 square feet); 54 x 269 = 14,526 kg (32,024 lb). Customer defined air dried solid oak boards. 5. Uncoated plywood: 12500 x 2750 mm Coated plywood: 12300 x 2700 mm. For example, if you have joists spaced 40 cm (16 inches) on centre with a span of 4.2 metres (14 feet), the load would be 462 kg (1,019 lb) per joist. These loads are recommended when engineering principles are used for design. All materials are supplied in a sawn finish as standard. First Grade kiln dried oak boards are often used in applications where little, or virtually no knots are permitted. RETAINING WALL ANALYSIS (BS 8002:1994) TEDDS calculation version 1.2.01.06 Wall details Retaining wall type Cantilever propped at base Height of retaining wall stem hstem = 3500 mm Thickness of wall stem twall = 350 mm Length of toe ltoe = 3000 mm … Open shelving or closed with rear braces: 5,400 lb. Plywood is often sold in 1/4″, 1/2″, and 3/4″ thicknesses, though other sizes are also available. Hopefully the highlighted part shows up, indicating the plywood of consideration. For single-span beams under uniform load, the total uniform load, w b, based on allowable bending stress in the web and flanges, can be calculated from the following formula: w b = 8 F b I n 12c L2 where w b = Total uniform load, based on allowable bending stress (lb/ft). Nordic Homeworx L.L.C. Table 5-11: Assembly Factors g19 for Plywood Loaded Normal to the Plane of the Plywood Panel 51 Table 5-12: Assembly Factors g19 for Plywood Loaded in the Plane of the Plywood Panel..... 52 Table 5-13: Duration of Load Factor j2 for Creep Deformation for Bending, Compression and Shear In the case of a floor, you can determine the load capacity fairly accurately with nothing more than the size, space and span of the floor joists. Engineered wood is a better … The spreadsheet is designed for stand alone use for many common situations requiring only information provided in the discussion … Most timber-framed systems can be analysed with the same general formulas. Products claiming compliance with this standard must also carry the specified markings, which includes a reference to EN 636. (Planed All Round) category. Calculate the weight of different species of lumber using our lumber weight calculator. But there are generic formulas, and when used as guidelines only, can be used to calculate plywood weight. Figure 1 Types of urban … Load calculations are quite complex and lend themselves well to the use of a spreadsheet.
