Floor joists in standard U.S. residential construction are supported on the outer walls by a foundation, typically cement block or concrete. Between outer walls, support may be necessary in the form of a support beam resting on posts which transfers load to a concrete pier.

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
Does a 4 X 8 X 16 steel beam need a center support when it has only one floor level that it supports. The room it supports is 16.5 foot wide?
you should be fine if you are just supporting the load of the floor. If you are putting increased load on the beam to support the roof somehow that could be a problem.
What is a load-bearing horizontal component?
Outside wall, inside partition wall, usually down the center of the house, header over a door or window, top and bottom plate in the wall, the floor the wall sits on, the rim joist the wall sits on, the floor joists, these are all horizontal load bearing features.
Factors that affect the size of ceiling joists?
The size of ceiling joists is primarily influenced by the span they need to cover and the load they must support. Other factors include the type of wood used for the joists, the spacing between joists, and any additional load considerations like heavy fixtures or storage. Local building codes and regulations also play a role in determining the size of ceiling joists.
What wall supports loads in addition to its own weight?
A wall that bears the load of a roof, floor or another wall above it, is carrying a load other than its own weight and is called a load-bearing wall.
How do you put in new joists when you have old joists in the stone foundation?
Joists are support beams made of timber (wood), steel, or reinforced concrete. These beams support the floors of each level of a house or building, as well as the roof.You need to first identify any trimmer joists, those around staircases or chimneys. Second, and most importantly, you need to identify the "load bearing" joists. Third, remember you cannot remove joists without FIRST installing a temporary joist right beside the one you intend to remove. Consult the DIY article in Related Links.The main premise in joist replacement is to correctly re-support the house with new load-bearing joists, but to do so, you must support the load with temporary supports before putting in the permanent replacements. This is accomplished with jacks that support the house and temporary joists. I'm NOT an expert, BUT if I remember correctly, once you've supported the main load points, you insert a temporary joist beside the old or support it on a jack for every joist throughout the area in which you are working, (e.g. a basement). Then you replace the highest load-bearing joists first. Last, you'd replace the lowest-load-bearing joists. So it is a 3-step process: (1) insert temporary joist right beside the old (2) remove/replace the old with the permanent joist with a correct load-bearing wood/timber/steel/concrete (3) remove the temporary joist.If you are not a construction worker, be sure to consult an expert first to get information about how to calculate the "load" factors for the specific house. You may want to hire a contractor to do the job.NOTE: If you remove existing joists incorrectly, the risk is that the load in that area is higher than in other areas, so the structure could:be weakenedexert a "twisting" on the structure due to load forcesbe damaged or may collapse.Disclaimer: This answer is formulated from knowledge gained when working with a contractor during home construction, BUT not as a skilled worker.

What size I-beam is required for a basement beam that needs to span 25 feet and will support 2x10 floor joists spanning 12 feet?
These calculations are not difficult, but you must know the load (including the floor weight) that will be carried. And the deflections that the appropriate building regulations allow.
What is the maximum span on a double 2x12 beam supporting 2x8 ceiling rafters and an acoustical ceiling?
Depends on the area above the ceiling joists. Is it a live load (living space) or dead load (just the joists with maybe an attic above)? Also, the length of the ceiling joists from the last bearing point is a factor. How much weight is bearing on the beam is the critical issue.
What does the term floor load mean when loading an overseas container?
The floor load in an overseas container is the amount of load the floor is capable of holding.
What and where is the neutral layer in a beam that supports a load?
The neutral layer is a beam that supports a load is in the region where there is neither stretching nor compression.
What are the types of non load bearing walls?
Non load bearing walls are walls that the weight of the roof is not supported on. Any wall that runs parallel will roof joists will be non load bearing.
What are four advantages of engineered wood floor trusses?
1.Designed for light-frame construction are often used in place of floor joists in residential structures. 2.The top chord are the horizontal flanges at the top and bottom of the truss. 3.The web is the framework between with the chords. 4.Engineered floor trusses are designed with the aid ensure accurate load capacities.
