  • Calculating live load

    If the deck was 200 sqft and 40 psf live load, the total live load would be 9600 lbs and the three columns would be required to support 9600/2 or 4800 lbs of live load in practice you would also include the dead load which is the weight of the materials.

  • Joist Layout for Stronger Decks Professional Deck

    For decks and the first floors of houses, residential code is based on a vertical live loading people and furniture of 40 pounds per square foot psf plus a 10-psf dead load the weight of the structure itself , for a total design load of 50 psf.

  • How to calculate my deck load capacity?

    Each member, that is a part of that deck has a load capacity. The load capacities are mainly determined by the area of the section modulus. For example, a 6x6 post has an area of 5 1/2"x 5 1/2" which equals 30 1/4" sq.in. Based on the species of wood and the 30 1/4 sq.in., the load capacity can be found for a 6x6.

For instance, if you know the dead load of the deck will be less than the prescriptive 10 lb., then you can select 5 lb. or 7 lb. and eek out a longer span.

  • Deck Load Design and Calculations

    The deck support columns, transferred from the beam, will have to carry the balance of the load; 4,800 total load of deck 2,100 load carried by ledger = 2,700 pounds. We also determined that the maximum load we want to carry on any one deck support column is 1,250 pounds. The calculation of 2,700 ÷ 1,250 comes out at 2.2.
