Our unbeatable deals on high-quality lumber are available today, ensuring you get the materials you need at a price that fits your budget. Fast, accurate, and user-friendly. 2) The shear force of 5. This document contains calculations to check the structural integrity of an 18mm plywood formwork facing for a retaining wall. This is particularly useful in construction and woodworking when creating curved surfaces. Use StruCalc’s wood beam calculator to size and check spans, loads, and deflection for floor, roof, and deck beams. Because beams are typically positioned on edge, use “thickness” to represent beam depth and “depth” to represent the thickness of the beam. . It depends on the type of wood, grain, dimensions etc. It calculates: 1) The bending moment of 0. Supports all major lumber species and grades. Professional saddle bend calculator for electricians. How to bend a piece of 3/4-inch plywood Stumpy Nubs (James Hamilton) 1. Uniform Loads Based on Deflection Requirements The following formulas may be used to calculate deflection under uniform load, or allowable loads based on deflection requirements. 87 kN, which is less than the allowed shear force of 7. For sawn lumber, in addition to the typical adjustment to weak-axis bending stress noted above, the flat use factor is also applied to the adjusted modulus of elasticity (E') and the adjusted modulus of elasticity for beam and column stability calculations (E'min) when minor-axis moments are present. W is the width of the plywood (ft) 4. Test your dimensions and cut depth on pieces of scrap The following formula is used to calculate a total load capacity of a piece of plywood: LC = L* W * MP 1. It works out the geometric spacing of the cuts so when bent, the inside edges of the cuts join to create the curve. Here's the simple answers by thickness. com, that some of you may find useful. This calculator can also be used to measure beam deflection. May 11, 2024 · The deflection limit, represented as “d” in the formula, ensures that the span calculated will prevent the plywood from bending excessively under load, which is vital for maintaining the structural integrity and safety of the construction. When bending plywood, drying may be hastened by laying a piece of coarse burlap over the radius bending form. Easily calculate LVL span limits based on depth, spacing, and load type using our LVL Span Calculator. This essential calculation ensures precise and effective woodworking, especially in projects that involve bending wood to achieve specific shapes. Rafters Drywall or no finished ceiling, construction load 20 PSF live load Sep 11, 2025 · Enter the material thickness, bend radius, and kerf width into the calculator to determine the kerf bend allowance. Plugging in your numbers (L = 34 inch, W = 20 inch, H = 3/4 inch, P = 300 pound-force), I calculate the bending stress to be 2720 psi. To maintain a factor of safety of 5, your material should therefore have a tensile strength of at least 13600 psi, or 13. 3) The deflection of 0. MP is the max pressure based on thickness (psf) The max pressure of the plywood can be estimate using this table: If you’re using common construction lumber, a 1 inch board is actually 3/4″ and a 2 inch board is 1-1/2″ thick. 4185 kN-m acting on the formwork, which is less than its allowed moment of 0. The optimum depth of the cut, and thus remaining minimum thickness of wood to obtain the curve cannot be calculated. To speed drying, a fan may be used to circulate air around the formed Plywood part. Changing member types automatically sets new defaults to the most common deflection limits, member spacing, and loading conditions. Splines get imported, but for better accuracy convert them to polylines Even better, if your CAD supports it auto-convert to lines or polylines (eg. 65mm under the applied load Online sheet metal fabrication service. in Rhino save as "2007-Lines") "Display Extra Geometries" shows the imported line, check for errors on complex curves Calculate kerf spacing for bending wood with printable full scale set out templates - Inch Construction calculators for estimating materials and costs for many renovation, remodeling, building, landscaping, concrete, siding, and roofing projects. L is the length of the plywood (ft) 3. Simple clicks on the drop down boxes will allow variable inputs to calculate a span. The part should be allowed to dry completely on the form. 6 kN. What is a Slot Spacing for Plywood Bending? Slot spacing for plywood bending refers to the distance between the slots cut into the plywood to allow it to bend into a desired shape. Where LC is the load capacity (lbs) 2. Jan 15, 2026 · Roseburg | Exceptional wood products build on more than 80 years of innovative thinking, cutting-edge design, and high-tech manufacturing. 7. Clicking on the Grade/Span Comparison calculator bar will allow size comparisons between different grades of Southern Pine. 02M subscribers Subscribe Sep 7, 2024 · This calculation determines if the plywood can support the expected load without bending or breaking. 6 ksi. Use this wood beam span calculator to check a wood beam of a particular size and length to see if it can support a given uniform linear load by comparing its allowable and required bending and shear stress. Apr 25, 2023 · Plywood is a common construction material, but it's not always clear how much weight it can hold. This calculator finds the spacing of the cuts (at entered dimensions), so when the piece is bent, the inside edges of each cut touch together to form the correct curve. Get custom parts delivered in just a few days—upload STEP or DXF files for instant pricing! There are a number of online calculators for computing beam deflection (a shelf is basically a beam placed on its side rather than on its edge) but many of these assume a knowledge of beam mechanics or require inputs that are somewhat esoteric or not readily available (such as the modulus of elasticity for various types of materials).
