Continuous span values given in the tables should only be used where: a). Neither SFPA, nor its members, have knowledge of the quality of materials, workmanship or construction methods used on any construction project and, accordingly, do not warrant the technical data, design or performance of the lumber in completed structures. Continuous Span Beams are beams supported at three or more points along their length. The conditions under which lumber is used in construction may vary widely, as does the quality of workmanship. Depending on its width, depth, and load parameters, an LVL beam can span up to 80-feet. The layers are heated, glued, and pressed together in different widths or thicknesses, and then cut to depths to meet various load requirements. Accordingly, neither SFPA, nor its members, warrant that the design values on which the span tables for Southern Pine lumber contained herein are based are correct, and specifically disclaim any liability for injury or damage resulting from the use of such span tables. Other manufacturers LVL may have different properties and therefore cannot be designed using these span tables. An LVL or laminated veneer lumber beam is made up of thin layers of wood veneer similar to plywood. The design values contained herein are based on the Southern Pine Inspection Bureau’s Standard Grading Rules for Southern Pine Lumber and modified as required by the American Wood Council’s National Design Specification® (NDS®) for Wood Construction. SFPA does not grade or test lumber, and accordingly, does not assign design values to Southern Pine lumber. Enter Single Span table at 450 mm in joist spacing column, read down to a span equal to or greater than 1700 mm.
Reference design values are for normal load duration under the moisture service conditions specified. These easy-to-use tables were compiled by the Southern Forest Products Association (SFPA) as a service to design/build professionals and other Southern Pine users. Select the correct table for the supported floor joist condition.
