Seeking guidance from a structural engineer is imperative to ascertain the precise size and specifications required to ensure safety and adherence to regulations. The dimensions of the beam will vary based on load considerations and the chosen material. To cover a 30-foot span, one can utilize either a multiple-ply 2×12 or opt for engineered wooden beams like LVL. These beams are often custom-manufactured to precisely meet the specific requirements of your project. As a general guideline, for a 30-foot span, it is typically recommended to use LVL beams with dimensions of 5-1/4″ × 13 1/2″ or 5-1/4″ × 16″. The size of LVL beams required for a 30-foot span is contingent on several factors, including the anticipated load and compliance with local building codes. A double 3 1/2 × 5 1/2 lvl beam can allow span up to 10 feet far distance used for residential building or projects. Flat Loading: 1.15kN/m2 Dead Load + 1.5kN/m2 Imposed Load. House Loading: 0.75kN/m2 Dead Load + 1.5kN/m2 Imposed Load. Once these have been entered, the joists suitable for this application appear in the table below. Steel beams reign supreme in this domain, offering unmatched load-bearing capacity and durability. A double 5 1/2 LVL is made by laminating of two 1 3/4 inches or 40mm thick and 5 1/2 deep LVL. This application will specify a list of acceptable JJI-Joists once you enter your support conditions, load case and clear span. ![]() When spanning a 40-foot distance, the choice of I beam becomes crucial. Download the design software here.Selecting the Optimal I Beam for a 40-foot Span For over 10 years the program has been under progressive and continuous development of engineering design techniques and innovations.įor novice or professional, NP Design is free, quick and easy to learn. NP Design is developed by leaders in engineering design software. A 3-ply with 2 X 10s would mean that three 2 X 10s are. It also shows the maximum that the beam can span for various numbers of such pieces of lumber built together (this is indicated by 3-ply, 4-ply and 5-ply). NP Design assists with certified specification of engineered wood products in common applications. This span table excerpt shows two possible sizes of built-up floor beams (2 X 10 and 2 X 12). NelsonPine® Design (NP Design) is a powerful design program for a range of user types, from builders to structural engineers and offers a range of different building levels to accommodate various user competencies. Sustainably Managed Timber NP Design – The Design Software for NZ and Australian Standardsįast, accurate beam specification for any project, domestic or commercial. In our new ‘post-quake’ consciousness, it is the building material of choice”– Professor Andy Buchanan, University of Canterbury. “Technically, LVL is one of the most sophisticated wood products ever developed for the construction sector. NelsonPine® LVL products inspire Architects, Designers, Builders and end users to realise structural applications. Our range of LVL products are designed to span further and weigh less to optimise efficiency in design and construction. VERSA-LAM ® laminated veneer construction (LVL) beams and headers eliminate twisting, shrinking and separation, plus deliver flatter, quieter floors and structures. Our NelsonPine® LVL is engineered from renewable and sustainably sourced New Zealand radiata pine. ENGINEERED WOOD PRODUCTS (EWP) LVL SPAN PLUS SIZE CHARTS. ![]() LVL is manufactured to achieve consistent strength, stiffness and stability. Built up with a specific sequence of structurally graded veneer sheets, the finished product displays less variability, a higher strength to stiffness ratio and more predictable performance than sawn timber. ![]() NelsonPine® LVL provides a consistent, high-performance alternative to solid lumber and steel in structural uses. member listed in the Span Tables is taken from Table 2.5 in AS1720.1:2010 - Timber structures, Part 1: Design methods, where for all LVL structural elements used in residential houses ø 0.95. Table assumes a maximum flooring mass of 40kg/m2. (2) Spans for floor joists that are not selected from Tables A-1 and A-2 and that are required.

Our products are used across residential, commercial, industrial, formwork and scaffolding applications. (1) Except as required in Sentence (2) and Article 9.23.13.10., the spans for wood joists and rafters shall conform to the spans shown in Tables A-1 to A-7 for the uniform live loads shown in the Tables. NelsonPine® LVL is available in a variety of sizes and lengths. NelsonPine® LVL is a structural engineered wood product manufactured from rotary peeled veneers, assembled with parallel grain orientation and bonded with an exterior structural adhesive.
