The size of wood used for floor joists typically ranges from 2x8 to 2x12 inches, depending on the span and load requirements of the floor.
For a deck, 2x8 or 2x10 joists are commonly used, depending on the size and load requirements of the deck.
The different types of floor beam support used in construction include joists, girders, and beams. Joists are horizontal supports that run perpendicular to the floor beams, girders are larger beams that support the joists, and beams are horizontal or sloping supports that carry the load of the structure.
For a deck, 2x8 or 2x10 joists are commonly used, depending on the span and load requirements of the deck.
If your house is wood framed with wood joists, the shaking may be caused by floor joists being too small. This will cause the floor to sink whenever a person walks across the room. Floor joists should be size by an experienced carpenter, architect, or engineer to prevent movement.Another cause of floor movement may be insufficient bracing between the floor joists. This will cause sagging and twisting of the joists.There are several solutions that require the skills carpenter. New joists can be added beside the existing joists to strengthen the floor. Another option is to add one or more beams and columns in the room below the floor. Or blocking can be added between existing joists to add support.
Common causes of sagging floor joists in a building include structural damage, excessive weight load, moisture damage, and poor construction. Solutions for sagging floor joists may involve reinforcing the joists with additional support beams, repairing or replacing damaged joists, addressing moisture issues, and ensuring proper construction techniques are used. Consulting a structural engineer or contractor is recommended for a professional assessment and appropriate solutions.
In a conventionally framed wood structure, you will find box/rim joists, floor joists, headers, braces, and some form of decking. There are many parts to a floor and more ways than one to build one. In timber framed building, you will find posts, braces, girts, joists, connectors, and other heavy timbers.

Yes, 2x6 lumber can be used for deck joists, but it may not be as strong or durable as larger dimensions like 2x8 or 2x10. It is important to consider the span and load requirements of your deck when choosing the appropriate size for joists.
all depends how the floor is constructed and the size of the joists, the span of the joists, thickness of floorboards. Is it a concrete floor. Is it a 'live' load like people of furniture or a 'dead' load like an unsupported wall. It the house an old building or of recent construction. A residential standard suggests 40lb per square foot. Needs confirmation though
Common causes of sagging floor joists in a house include structural damage, excessive weight load, moisture damage, and poor construction. Solutions may involve reinforcing the joists with additional support beams, repairing or replacing damaged joists, addressing moisture issues, and ensuring proper construction techniques are used in any repairs or renovations. Consulting with a professional contractor or structural engineer is recommended for accurate assessment and appropriate solutions.
For a mobile home floor, typically 3/4 inch thick plywood is recommended for optimal strength and durability.
