The design is based on floor dead loads up to 40kg/m2, live loads of 1.5KPa distributed and a 1.8kN concentrated load. For each combination of span and thickness (or Span Rating), loads are given for deflections of L/360, L/240 and L/180, Spacing should be interpreted as the centre to centre distance between adjacent parallel members. Floor Joist Span Tables for various Sizes and Species of Wood. 4) See A.1.3 for 2 span floor joist requirements. Table 9.1 in Span Tables for Joists and Rafters (Figure #5) gives a required compression value of 237 psi for a span of 16 feet and bearing length of 1.5 inches.

She’d like to create the look of a high-pitched ceiling, under which she could add a mezzanine floor. To do this, multiply half of the total horizontal span supported by the column by half of the total vertical span supported by the column. Load capacity, floor type, access options, safety features and building obstructions are only a few factors to consider. Floor capacity depends on the thickness of the concrete and how much the soil underneath the slab will compress. 2 Grade of Douglas fir are indicated below. Floor live load exceeding 1.5kPa (2.0kPa for balconies) requires engineering calculations. 2 lumber is used for each extension platform joist. The span table for a 30 psf live load/10psf dead load floor indicates a required Fb value of 1,315 and a minimum E value of 1,800,000. Knowing the characteristics of both the floor and underlying soil Maximum floor joist span for No. The first step is to calculate the square footage the column is supporting. Double span load capacities are based on the consideration of a uniformly distributed load on both spans or on one span … For now and forever solutions for a mezzanine floor. In the example, the joists have a spacing of 16 inches and a span of 11 feet, 2 inches. This table is for a dead load of more than 0.25 but not more than 0.50 and allows for an imposed loading of no more than 1.5 kN/sq.m. Designing a mezzanine solution can be a complicated process. Max. When you start loading a floor with tons of equipment, you must know its actual capacity. Mezzanine floor, 4.2m wide (from centre of garage to right side of garage), X 2.9m deep.
