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. Use this calculator to find out the beam span and deck footing size for your project.

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.

She has vast experience with digital media, including SEO, photo shoot production, video production, eCommerce content, print collaboration, and custom sales content.

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.

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.

It quantifies the resistance of the beam to bending under an applied load. The location where you live plays an important role in choosing wood for your joists. Decking Calculator. The following guide will walk you through basic deck requirements and best practices for calculating deck joist and beam spans. Clearcalcs Free Beam Calculator easily determined that the above example sags 0. They provide stability and distribute the weight of the floor to the supporting walls or beams. Deck beams are horizontal beams used to support the deck or balcony structure. Do it with the brand that invented composite decking, backed by , and year limited warranties. The calculations below list approximate recommended deck beam spans. Consult with a lumber dealer and your local building department before using hem-fir.

The ClearCalcs beam calculator allows the user to input the geometry and loading of a beam for analysis in a few simple steps. They are typically installed parallel to each other and help distribute the weight of the ceiling to the surrounding walls or beams. The user inputs the name, magnitude and location from the left of the beam. It is designed to support the weight of the roof and transfer it to the supporting walls. This makes for a more attractive, unobstructed view from your front windows. An appropriate beam size is typically determined by iteration: testing different cross sections sizes and assessing the load utilisation before coming up with the most efficient design. A shallow footing is allowed in warmer regions, but codes will specify a minimum amount of mass in the footings. 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. Joist Span Calculator. The calculator will apply the loads.
