18 Foot Beam

What kind of beam would i need to construct to bear this load.

18 foot beam.

Our beams are sold by the linear foot lf up to 40 lf available in even lengths. Beams of more than one ply must be fastened together with either nails or bolts. This is in hawaii so no snow. For example if you are using an lvl beam with two plies of 16 inches or three plies of 14 inches with the columns spaced 14 feet from one another the maximum span size is 36 feet.

I was thinking along those lines. The beams are simply supported. Floors supporting additional stories or roofs require sturdier construction and use different lvl span size charts. We have learned from our experience to use at least a 3 1 4 x 131 groove shank nail in a column of four every foot apart down the laminate.

The 2012 irc code calls for a minimum of a 32 o c. It supports a concrete floor carrying 1 8kn m2 finishes and live load of 2 5. You will need to provide solid mechanical connections between each of your floor joists and the top flange of the steel beam to provide lateral bracing support. The roof is a basic 7 12 gable with 2x6 joists and rafters.

The 18 feet 5 488m beams are spaced at 12 feet 3 66m centres. Your questions lacks information so i am going to assume them. You can use 2 or 3 18 lvl 10 12 whatever u like and put a good solid post on each end 3 2x6 nailed to each other should do just fine. With wings the maximum beam is 14 feet for the international 18 and 18 feet for open 18 s sailed at sydney flying squadron and skiffs australia.

This beam is 5 wide 13 875 deep and weighs 26 pounds per foot of beam. The main beam at one end will have to span the entire width 18. When the boat is dry it should weigh not less than 375 lb 170 kg including wings foils centreboard and rudder and the number one rig of sails spars and ropes. I had it in my mind to use 4 2x10s though.

I am removing a partial bearimg wall and putting in a full lenght beam instead over 18 ft. It will be covered with tin.
