Read the beam size or choice of beam sizes from table. Choose the required beam span in the left column. 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. Select the correct table for the beam application you need. You'll also need a new column the same size directly below it in the basement. Features and Benefits: -LVL Flange for superior strength and a. The intermediate bearing post will have 18,000+ pounds on it, so you'll need a PSL or steel column. L/480 is the design criteria we recommend for the best performing floor.

The conditions under which lumber is used in construction may vary widely, as does the quality of workmanship. The best solution to open this up is to run a 3 ply 11-7/8' LVL full length but with an intermediate support in the middle making two 9.5' spans with 1 beam. 2.0E GP Lam LVL Window and Patio Door Headers, 2-Story Span A Span B for table below Two-Story Applications This table shows the size (e.g.: 211149 2 plies of 1349 x 11149) of beams needed to support the combined loads from a wall, second story floor (14 of total floor joist span) Roug and various roof truss spans with a 2 soffit. 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. 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.

Span Tables Overview Resources provide a simplified system to determine allowable joist and rafter spans in one- and two-family dwellings, and the companion supplements for tabulating allowable bending and modulus of elasticity design values for visually graded and mechanically graded dimension lumber. For 2-Ply, 3-Ply and 4-Ply LVL members, the values in the tables may be multiplied by 2. Bearing wall, onCENTER LVL or glulam beam. All floor span tables in this guide reflect this enhancement. Reference design values are for normal load duration under the moisture service conditions specified. Diagram applies for simple and multi-span applications with. lumber (LVL) flanges and an enhanced OSB web. 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.
