What size joists should be used for a deck?
For a deck, 2x8 or 2x10 joists are commonly used, depending on the size and load requirements of the deck.
What are the different types of floor beam support used in construction?
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.

Why does upstairs shake when walking?
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.
What are the Types of floor joists?
There are several types of floor joists commonly used in construction, including solid sawn lumber, engineered wood joists (such as I-joists and laminated veneer lumber), and steel joists. Solid sawn lumber is traditional and widely available, while engineered wood joists offer greater strength and span capabilities with less material. Steel joists are used for commercial and industrial applications due to their high load-bearing capacity and durability. Each type has its own advantages depending on the specific requirements of a building project.
What are the common causes and solutions for sagging floor joists in a building?
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.
Name the basic components used in floor framing?
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.

When is a beam required under the floor joist?
A beam is required under the floor joists when the span between the joists exceeds the allowable limits for the materials used, which can lead to structural instability or excessive deflection. Additionally, beams are necessary when there are changes in load direction, such as supporting a load-bearing wall or when the joists need to be reinforced in areas with heavy loads. They help distribute weight more evenly and ensure the overall integrity of the floor structure.
How much weight can your floor hold?
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
Can you use 2x6 for deck joists?
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.
What is a sister joist?
A sister joist is an additional joist that is installed alongside an existing joist to provide extra support and strength to a floor or ceiling structure. This technique is commonly used in construction and renovation to repair or reinforce damaged joists, improve load capacity, or reduce floor vibrations. By "sistering" joists, builders can extend the lifespan of the flooring system without completely replacing the original joists.
