Q: How far can a lvl beam span? Tips for calculating and comparing.
A: The span of an LVL (laminated veneer lumber) beam depends on several factors, including the type of material, size, and intended use. Here are some tips for calculating and comparing LVL beams:
1. Determine the load requirements: The maximum span of an LVL beam will depend on the weight load it needs to support. This load can come from dead loads (the weight of the structure itself) and live loads (the weight of people and objects inside the structure).
2. Determine the length of the span: The longer the span, the larger the beam required to support it. Determine the exact length of the span you need to cover.
3. Determine the size and grade of the LVL: The size and grade of the LVL will depend on the load and span requirements. The larger the beam, the more load it can support. The grade of the LVL refers to its strength and stiffness.
4. Consult span tables: LVL manufacturers typically provide span tables that allow the user to determine the size and grade of LVL required for a given load and span. These tables should be consulted when selecting an LVL beam.
5. Consider other factors: Other factors that may affect the span of an LVL beam include the spacing of supporting elements (such as columns), the type of connectors used to join the beam to other elements, and the moisture content of the beam.
Ultimately, the exact span of an LVL beam will be determined by a combination of all of these factors. It is important to consult with a structural engineer or other qualified professional to ensure that the beam is appropriately sized and installed for its intended use.
