Glued laminated timber, or glulam, is a highly innovative construction material. Choose from a wide variety of steel and wood shapes. In other words, it is either going to be on an outside wall, or somewhere on the inside. An interactive drawing area allows you to design complex, multi-span beams in minutes. Wood I Beam™Floor Joist 20 LL/10 DL 40 LL/10 DL 20 LL/10 DL Extend floor sheathing to outside face of wall blocking or FiberStrong® rim board required at bearing for lateral support Rafter PAGE8GEORGIA-PACIFIC WOOD PRODUCTSAPR 2015ENGINEERED LUMBER RESIDENTIAL GUIDE Roof Joist Maximum Spans Table continues on next page. On longer spans the beam may require much more bearing space as indicated by this table. The beam calculator is a great tool to quickly validate forces in beams. beam calculator uses these equations to generate bending moment, shear force, slope and defelction superposition. worried about design codes and comparing beam demand and beam capacity, try out our easy to use According to the 2012 IRC codes any beam, joist, or header shall never have a bearing of less than 1 1/2″. The 2012 IRC code calls for a minimum of a 32″ O.C. Beams of more than one ply must be fastened together with either nails or bolts. solutions to the beam configurations shown on this page (simply supported and cantilver beams). We have learned from our experience to use at least a 3 1/4″‘x.131″ groove shank nail in a column of four every foot apart down the laminate. Fastening. Works with evenly distributed loads only. Pound for pound, glulam is stronger than steel and has greater strength and stiffness than comparably sized dimensional lumber. and concrete beams under various loading conditions. If you need full design checks via AISC 360, NDS, ASD and LRFD for steel or wood beam design Increased design values, improved product performance, and cost competitiveness make glulam the superior choice for projects from simple beams and headers in residential construction to soaring arches for domed roofs spanning more than 500 feet. Most interior beams need to include the roof load. diagrams, deflection curves, slope and tabulated results. If you have a steel, wood or concrete beam with complex boundary conditions and loads Beams of more than one ply must be fastened together with either nails or bolts. Nominal Size: Actual Size : Weight / Foot ** 1 X 3.75 X 2.5: 0.47: 1 X 4.75 X 3.5: 0.64: 1 X 6.75 X 5.5: 1.00: 1 X 8.75 X 7.25: 1.32: 1 X 10.75 X 9.25: 1.69: 1 X 12.75 X 11.25: 2.05: 2 X 3: 1.5 X 2.5: 0.94: 2 X 4: 1.5 X 3.5: 1.28: 2 X 6: 1.5 X 5.5: 2.00: 2 X 8: 1.5 X 7.25: 2.64: 2 X 10: 1.5 X 9.25: 3.37: 2 X 12: 1.5 X 11.25 : 4.10: 2 X 14: 1.5 X 13.25: 4.83: 3 X 3: 2.5 X 2.5: 1.52: 3 X 4: 2.5 X 3.5: 2.13: 3 X 6: … Properties, English Calculate the size needed for a beam, girder, or header made from No. According to the 2012 IRC codes any beam, joist, or header shall never have a bearing of less than 1 1/2″. These small areas are usually door opening on the interior and people are trained that these areas are the strongest place in a house to be in the case of an emergency. you're better off solving the problem numerically with one of our finite element analysis tools. It has been my experience to never use a beam smaller than a two ply 2 x 8. The only time you would ever need to use bolts would be if the material had such severe deformities such as a bad “cup” which could not be overcome by nails. Diagrams, Cross Section If there is are any questions about anything else, then you should contact your supplier or an engineer. interface. moment diagrams, deflection curves and slope curves for simply supported and cantilvered beams. steel, wood The Euler-Bernoulli equation describes a Also, remember, you can add results from beams using Shear & Moment Calculator. A free, online beam calculator to generate shear force diagrams, bending you're not We make elegant, powerful structural engineering and structural analysis software. This calculator takes all of this into consideration. UÊÊ- i ÊÃiÀ iÃÊ>ÀiÊ>Û> >L iÊ Ê`ii«iÀÊ depths by special order. Change dimensions to recalculate. Covers any span and every load with pin point accuracy. This calculator matches up with 90% of the applications in the 2012 International Residential Code book. (meters, kN, kPa), method of Wide flange beams are designated by the letter W followed by the nominal depth in inches … Beam Designer tool. AISC steel, NDS wood shapes Of course, it is not always possible (or practical) to derive a closed-form solution for some beam Then scroll down to see shear force diagrams, moment diagrams. The simplest form of this equation is as follows: The Shear Force and Moment can be expressed, respectively, as: We use these equations along with the boundary conditions and loads for our beams to derive closed-form together English (inches, kips, ksi) ... NDS, ASD and LRFD for steel or wood beam design and you want to design your next beam in minutes, you might like our Beam Designer tool. with shape properties to help you meet the demands on your beams. Try some of our staggered pattern with at least a 3″x.120″ nail. relationship between beam deflection and applied external forces. Wood I Beam joists are produced at a lower mois- ture content, thereby minimizing the effects of shrinking, twisting, and warping. AISC Steel and NDS Wood Design LRFD and ASD Design Checks and Load Combinations. superposition. In modern lumber practices, the boards are no longer exactly 2 x 4 inches when first cut, but today's drying and planing methods still leave the board 1 1/2 … You only have to select all of the loads that apply. (inches, kips, ksi), Metric the method of Anything 5′ and above we always at least double cripple. 2 pine or LVL. configurations. Its either going to an exterior or an interior load. Use it to help you design Maximum Beam Span in Feet-Inches (metres) Size of Beam in Inches x Inches (millimetres x millimetres) 2 X 8 (38 X 184) 2 X 10 (38 x 235) 2 X 12 (38 x 286) 3-ply: 4-ply: 5 … The load on an outside wall with clear span trusses is exactly half the load on each wall. Tutorials, Calculators, and Building Codes. This calculator is based on Euler-Bernoulli beam theory. (Example: Per … other free tools: Shear and Moment On longer spans the beam may require much more bearing space as indicated by this table. Double check yourself with these span charts. Originally, a 2 x 4 was cut as a rough green board that was exactly 2 x 4 inches in size, but by the time the boards were dried and planed, the boards became smaller, approaching the now-standard 2 x 4 dimensions of 1 1/2 x 3 1/2 inches in size. Wood Beam Calculator | What size do I need. For example, if  building is 24′ x 24′ and has trusses, and the load on the roof will be for 30 lb snow load and a ceiling with no storage will total out like this. This will amount to twice as much load on the exterior walls compared to a building with a center wall. The There are two different types of loads. Design multi-span beams with complex loads with WebStructural's intuitive Available depths and lengths. and you want to design your next beam in minutes, you might like our Easy to read, printable and comprehensive design reports. • Beam Sizing: Our heavy timber beams are cut to Standard Dimensions.
