Also, please take note that in this example of how to find support reactions and in the beam load calculator, we assumed that the beam is weightless. Multiply the maximum bending moment of 900 foot pounds by 12 to get 10,800 inch-pounds. Beams are the major load-bearing horizontal elements, while joists are secondary ones. how much weight can a 2x10 support horizontally how much weight can a 2x10 support horizontally. The support forces F3 and F4 can be calculated (500 kg) (9.81 m/s2) + (500 kg) (9.81 m/s2) = R1 + R2 => R1 + R2 = 9810 N = 9.8 kN Note! Tripling these species would result in spans that are 2 less than the tripled SYP beam. Providing better information on softwood and hardwood. Raised floor homes look great and protect homeowners against risks from flooding and subsiding soils. From my calculations and various span tables, everything is stronger than required except the 3x10 members . Bedroom floors typically are rated for live loads of 30PSF, living areas for 40PSF, unoccupied attics for 5PSF, and storage attics for 10PSF, while all also have a dead load of 10PSF or 20PSF to account for building materials.
