Deck beam span calculator

Deck beams and joists go hand-in-hand as the framing materials for your deck, deck beam span calculator. 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.

Building a deck? Then you need to know how to compute the spans for it to be structurally sound. These tips and this information will help. Building a deck can create an outdoor oasis for entertaining , but the project must be safe and structurally sound, with proper decking beam spacing, so you can enjoy your deck for years to come. Five basic components make up any deck: decking, joists also known as a ledger when attached to a house , beams, posts, and footings. To ensure that a deck is safe and strong, local building departments have strict code requirements for these components.

Specify beam geometry and loads to get started analysing the beam. The beam calculator automatically uses ClearCalcs' powerful finite element analysis engine to determine moment, shear, and deflection as you work. Start your free ClearCalcs trial to unlock saving and export, as well as even more calculators for wood, steel, and concrete beams, columns, and footings. Experience the full power of ClearCalcs with a 14 day free trial and start being more productive. 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. Position of Supports from Left allow the user to input any number of supports, and specify their position along the length of the beam. 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. A minimum of one fixed support, or two pinned supports are required.

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. For example, joists spaced 16 inches from the center of the joist next to it can span 1.

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. According to our beam span chart resource , the span of a beam is dependent on a few variables: the species of lumber, size of lumber, and the load it carries. Some of the most common types of wood used for beams include:. All are high-quality woods to use for framing purposes, however, your geographic region plays a role in which woods will be available to you.

Deck beam span calculator

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.

By simply selecting the member from the member selector or manually inputting the material type, dimensions, and length, the calculator quickly calculates the weight of the beam. Your Joist Span Calculator Results. Depending on the size of the deck itself, whether your joists are spaced either 12 inches or 16 inches from the center, and the framing materials and size of deck boards used, deck joist spans may vary. Beam: 4x10— Joists span up to 10': Beam span: 8'. ClearCalcs provides a ridge beam calculator , which helps engineers determine the appropriate span and size of ridge beams based on the specific roof design and loading conditions. It is the result of transverse loads applied to the beam and plays a significant role in determining the beam's structural integrity. They are typically installed parallel to each other and help distribute the weight of the ceiling to the surrounding walls or beams. By populating the loads and design conditions, users can view the shear force diagram, bending moment diagram, and deflections. The farther decking beam spacing is—the farther apart the posts are—the more massive a beam must be. They make for a stronger, straighter, safer, and smarter alternative to wood substructures and may be more economical in the long-run. Deck Beam Spans— Distance between ports, using No. Your local building department has regulations designed to ensure a solid and durable deck. The ClearCalcs Free Beam Calculator can be utilised to assess continuous beams moment demand, shear demand and deflection by inputting as many fixed, pinned and roller supports as required. While joists provide a horizontal support system for deck boards, beams provide support for the joists. Beam deflection refers to the degree of bending or deformation that occurs in a beam under the applied loads.

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.

There are also strength differences between Redwood, Fir, Pine, and other types of wood. Beams and Footings Calculator. Two different types can be applied in the calculator:. Railing Calculator. Start your free ClearCalcs trial to unlock saving and export, as well as even more calculators for wood, steel, and concrete beams, columns, and footings. This information is then used to generate a bending moment diagram, which provides a visual representation of the bending moment along the beam. Looking for a retailer to buy your decking supplies? Use profiles to select personalised advertising. Beam span refers to the length between two adjacent supports of a beam. Even if you like the look of Redwood, it may not be the strongest material available to you. Learn More About Joists. Baluster Spacing Calculator. Each load can be named by the user. By examining shear and moment diagrams, engineers can determine critical locations and identify areas of high stress or deflection. This means there are fewer holes to dig and fewer posts to look at from the ground floor of your home.
