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. or exceed the requirements for strength class requirements defined by European LVL producers according to the following table: Type: Density 510 kg/m 3: Density 440 kg/m 3: Beams, joists, studs, formwork. NP Design is developed by leaders in engineering design software. Calculate live load: Choose a beam with a capacity that is equal or higher in the column for live load. NP Design assists with certified specification of engineered wood products in common applications. Pollmeier LVL 2.1E Design Guide Single Span Load Tables - Floor Load 04 - 21 - US Sheet 6 /29 How to use maximum uniform load tables 1. 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. Spans for Joists, Rafters and Beams (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. VERSA-LAM ® cover veneer lumber (LVL) beams or headers eliminate twisting, shrinking and split, and deliver flatter, calmer floors both structures. In our new ‘post-quake’ consciousness, it is the building material of choice”– Professor Andy Buchanan, University of Canterbury. ENGINEERED WOOD PRODUCTS (EWP) LVL SPAN AND SIZE CHARTS. “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. Our NelsonPine® LVL is engineered from renewable and sustainably sourced New Zealand radiata pine. Spans in construction refer to how long a structural element, like a beam or a joist, can be before it needs support from something else, like a wall or a column. LVL is manufactured to achieve consistent strength, stiffness and stability. Span tables allow users to choose an appropriate size and stress grade to achieve spanning needs. 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. Our products are used across residential, commercial, industrial, formwork and scaffolding applications. 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.
