Deck beam span calculator

Building a deck?

Deck beams and joists go hand-in-hand as the framing materials for your deck. While joists provide a horizontal support system for deck boards, beams provide support for the joists. Your beams will need to bear the load of not only your decking materials, but additional components of the frame itself. Use this calculator to find out the beam span and deck footing size for your project. Be sure to have your joist span calculations ready to enter for an accurate reading and check out our concrete calculator to determine the size of your footings. Three tiers of premium composite and aluminum deck and porch railing provide low-maintenance options for all tastes and budgets.

The ClearCalcs beam calculator allows the user to input the geometry and loading of a beam for analysis in a few simple steps. It then determines bending moment, shear and deflection diagrams, and maximum demands using a powerful finite element analysis engine. Signing up for a ClearCalcs account will unlock further advanced features for design and analysis of beams and a variety of other structural elements. Area of the Cross-Section is specific to the beam section selected, and is defaulted to the values for a common steel beam. Second Moment of Area or Moment of Inertia is also specific to the beam section selected, and again defaulted to the properties of a common steel beam. The properties E, A, and Ix for other beam sections can be obtained from the ClearCalcs section properties library.

Alternately, you can create your own custom section using our free moment of inertia calculator. Second Moment of Area or Moment of Inertia is also specific to the beam section selected, and again defaulted to the properties of a common steel beam, deck beam span calculator. Clearcalcs Free Beam Calculator easily determined that the above example sags 0.

Each joist is one of a series of long, horizontal structures that support the decking itself. While posts are vertical, joists lay horizontally on top of each beam to provide a sturdy, level surface to lay your decking materials across. Joists can be made from wood or steel. Use the joist span and spacing calculator below to plug in your desired type of wood, the size of your joists, and the required spacing between each joist. Do it with the brand that invented composite decking, backed by , and year limited warranties. As a rule, the larger the deck, the larger the joists.

A beam is a solid structural member that is supported by posts and footings that accepts and transfers the load from joists. Once you know the distance between support posts and the length of the joists that will be supported you can determine the required size by checking our beam-sizing chart. The size of a beam is a function of the amount of weight it must support and the distance it must span. A common beam is composed of the same size and type of lumber used for the joists by nailing 2 or 3 together side by side. Even if you are allowed to use a smaller beam, you should maintain the same depth of material as the joists to present a uniform appearance. The relationship between directly applied and fastened boards is what bonds the strength of a multiply beam. Occasionally a beam application may require spanning a long distance that exceeds the design limits for conventional beams.

Calculating the load on a beam is an essential step in structural analysis and design. The beam calculator automatically uses ClearCalcs' powerful finite element analysis engine to determine moment, shear, and deflection as you work. The ClearCalcs Free Beam Calculator cannot calculate load on the beam like the ClearCalcs Design Calculators but can demonstrate the effects of specified loading that can be found through standards and prior calculations by the user.

Shear force is the internal force within a beam that acts parallel to the cross-section. Deck Beam Spans— Distance a joist spans between a beam and a ledger or between beams, using No. By analyzing the diagram, engineers can identify critical points where the shear force is at its maximum or minimum. By inputting the loads and beam properties, the calculator determines the shear force at different points along the length of the beam. Specify beam geometry and loads to get started analysing the beam. For example, these can represent reactions from other members connecting to the beam. Below is the load outputs detailed on the example we have been working through. With this in mind, the joist span can range between 6 ft, 10 inches, to 18 ft. Some hem-fir is solid and stable, while some is weak and likely to warp and crack. By populating the loads and design conditions, users can view the shear force diagram, bending moment diagram, and deflections.

Each joist is one of a series of long, horizontal structures that support the decking itself.

Lumber quality also has a bearing on a board's strength. ClearCalcs even has built in standard section sizes to ensure your beam design can be procured easily from a local manufacturer. The following guide will walk you through basic deck requirements and best practices for calculating deck joist and beam spans. There will be less waste too. It helps distribute the load from the structure above to the surrounding walls or columns. Boards graded No. The support type can either be pinned fixed in translation, free in rotation or fixed fixed in both translation and rotation and is selected from the drop-down menu. By analyzing the diagram, engineers can determine the required size and reinforcement of the beam to ensure it can safely resist the applied loads without exceeding its bending capacity. Different support configurations result in varying levels of beam stability and load-carrying capacity. Here are some common beam support types:. Beam span refers to the length between two adjacent supports of a beam. Second Moment of Area or Moment of Inertia is also specific to the beam section selected, and again defaulted to the properties of a common steel beam. Positive values imply a downward deflection and negative values imply an upward deflection. Users can input key properties of custom sections or use the member selector database. The ClearCalcs Free Beam Calculator allows users to input the different types of loads acting on the beam, including dead loads, live loads, and other relevant forces.
