Joists can be supported using various methods, including traditional wood beams, steel beams, or engineered wood products such as laminated veneer lumber (LVL) or I-joists. They can also be held up by using column supports or posts that transfer the load to the foundation or floor below. Additionally, hangers can be employed to attach joists to beams or walls, providing stable support. Each option should be chosen based on the specific structural requirements and building codes.
That depends upon the size of the joists & grade/species of wood
It will hold up the human body if it is placed on it. Technically, the effect will be that it will hold the body off the subflooring and floor joists.
Ceiling joists can typically hold between 10-20 pounds per square foot, depending on the material and size of the joists. It is important to consult a structural engineer or building code regulations for specific weight limits in your area.
Better put them in. Something has to hold the roof or roof panels up and prevent them from holding water.
The best options for covering deck joists to protect them and extend their lifespan are using a waterproof membrane, applying a sealant or paint, or installing a protective metal flashing. These methods help prevent moisture damage and decay, ensuring the joists last longer.
Try not to invite Aretha Franklin and Queen Latifah over for dinner and your floors should hold up just fine.
That depends on how well supported the floor is and that depends on how far apart the joists are placed. The closer they are, the more weight can be supported.
Generally, the horizontal members in a building are called beams. Beams can be girts, which hold up joists, headers, which are found above windows, plates, that hold up rafters, etc. Beams are usually structural members.
Any joists which are not straight shoud be positioned with the camber or crown (curved edge) upwards. When loaded these joists will tend to straighten out rather than sag further if laid the other way up!
You're going to have add columns supporting the bottom and top of the stringers.Or you can double up the joists on either side of the top and thru-bolt them to stringers.You'll have to double or triple up the joists below the stringers (depending on the span of the joists)
Almost all members in a timber frame house are structural. Think of a timber frame as a skeleton, just like all the bones in a body are structurally important, all the parts of a timber frame are important. Posts hold up the girts, which hold the joists, which hold the floor. The posts also hold up the rafter plates that hold up the rafters and roof system.
Yes. Rafters and flloor joists do not have to run the same direction.
