Size and spacing are very important to install floor joists properly. Their spacing (16" or 24" on center) is critical to engineering
safety, and they must be perfectly flat and level, or the floor will be uneven. The wider the span between the supporting structures (beams,
sills, rim joists), the larger the joist (2" x 8", 2" x 10", etc.) will need to be if it is not to deflect under load. There are approved formulas for
calculating the depth required and reducing the depth as needed; however, a rule of thumb for calculating the depth of a wooden floor joist
for a residential property is half the span in feet plus two inches; for example, the joist depth required for a 14‑foot span is 9 inches. High
quality wood must also be used, as bending and warping in the joists will throw the floor and the building out of plumb, causing structural
problems and safety issues. In addition, floor joists are installed at a very early stage in the building process, and in older structures, they
may eventually need to be replaced as a result of bowing, crowning, water damage, termite damage, or if they were installed improperly
when the building was designed or constructed.

"The most common cause of joists, beam, and rim joists
failures are poor spacing, water, and termite damage".
Crawl Space Foundation Floor Joists
In architecture and engineering, floor joists are a series horizontal dimensional wood or wood
trusses laid out in repetitive patterns that support the floor or ceiling loads. In a typical home,
the surface flooring (such as hardwood, carpet or vinyl) rests on a sub-floor, which rests on floor
joists.

Floor joists run from wall to wall, wall to beam, or beam to beam to support a ceiling, roof, or
floor. They are an important part of the supportive structure of a floor and are usually supported  
by beams, sills, rim joists, or foundation walls. They hold up the weight of a building, absorb
impacts on the floor, and create structural support so that the floor will be stable and secure.

What Are Floor Joists, Structural Beams, Rim Joists, and Sub-Floors?

What Can Go Wrong and How to Repair Them

Wood rot, water or termite damage ;  In most of these cases, the damaged sections of the beam will have to be completely
replaced.  This is a difficult and potentially dangerous process, so make sure the company you hire are experienced professionals.  The
beam that is replaced should be the same size as the previous beam, and possibly may need additional piers or columns to support the
beam.  A common but improper repair that we have seen in the field all too often is to sandwich the damage beam with new boards and
bolts.  While this will hold up the house, it is not a permanent repair and may will not pass a home inspection when you sell the home.

Sagging and/or over-spanned:   The beam will sag from high moisture content in the crawl, and if the beam is over spanned
between the pier columns.  In either case, the proper repair is to reinforce the middle of the span of the beam with new footings and block
piers columns.  We recommend in most crawls paces, that the new pier columns be made of masonry blocks.  Screw Jacks are made of
metal and have a tendency to rust out at the bottom where they are touching the ground floor.  Cinder blocks will not deteriorate and
are the material that builders trust.
A structural beam (or girder) is a horizontal structural element that supports the load of the
floor joists. A structural beam transfers the load it carries on to the pier columns, sills, or crawlspace
foundation wall.  Beams can be made up of wood, steel, or reinforced concrete. Most often crawl space
foundation beams are made up of two-three boards of 2×8 or 2×10 lumber sandwiched together by
nails or screws.  Typically the center beam runs down the middle of the home transferring the load of
the joists between the piers.  The piers should be spaced according to the size and strength of the beam
installed.
A softened, damaged, or over spanned beam will require different solutions for its repair.  It is
important to repair the exact problem the beam is experiencing as a one size fits all approach (wood
post or screw jacks) will not always work.  A home’s center beam can experience several different
problems.

To repair this problem correctly, the floor and wall will need to be raised enough to replace the
damaged rim joist. The extent and cost of rim joist repairs depends upon the degree of the damage. If
them, the rim joist might be okay. If water damage caused by an improperly installed deck or door are
found early enough, the rim joists can also be saved. If the rim joist can no longer adequately support
found early enough, the rim joists can also the wall above, it may require removal and replacement.
This is a costly repair, especially if the damage is in a rim joist that runs parallel to the floor joists, since
this specific rim joist bears more load than the ones running perpendicular to the floor joists. If the rim
joist is in bad shape, the sill plate, floor joists and wall studs may also have damage that requires
replacement or reinforcement.
Repairing the rim joist can be dangerous, and should only be done by an experienced professional. Make sure that these building
professionals have experience and understand how much weight they are dealing with. In most cases, damage to rim joist will create
sometimes ceilings to sag.
or carpet). The joists support the sub-floor the sub-floor is attached to the tile, hardwood or carpet. These structural elements of a building
make up part of the sub-floor, the structure that goes underneath the flooring that people walk on. Sub-floors are designed to provide
support to the flooring, and to make the building itself more rigid and stable so that it will withstand years of heavy use. They connect
with the supportive framework of the structure to reinforce it. Plywood is the most common sub-floor material in recently built homes.
Older homes typically have 3/4-inch thick  4- to 8-inch pine. Oriented Strand Board (OSB) also can be used for sub-floors.
All of the most common sub-floor materials are wood-based and susceptible to termite or water damage.
In fact, termites prefer these softer woods to hardwoods and may cause significant damage to the
sub-floor before feeding on hardwood floors. Over time, a sink, toilet or refrigerator water leak can
damage and even destroy flooring materials and the sub-floor below it. The damage can go undetected
for a long time or during the course a home improvement project, you will run across this unexpected
obstacle. In preparation for a new floor (tile, wood or sheet), there may be a section of the sub-floor which
is too "bouncy" or soft. There are many variables that will contribute to this situation. Support, quality
of the material, or adequate thickness, the fact is; this section of the damaged sub-floor will have to be
replaced.

The rim joist (also known as a band board or header joist) is also a part of the
foundation of a home. Like the floor joists, its primary job is to support the exterior
walls as well as giving the floor joist an adjacent surface to be attached. The floor
joists sometimes rest on a sill plate and are capped by a rim joist that is nailed to
their ends. It keeps the joists true and provides a flat surface for backing the edge of
sub-flooring and the base of exteriorwalls. In effect, it completes the “box” of a floor’s
structure.

The rim joist, holds up the wall, which holds up the roof. An idea of how much
weight can actually be supported by a single rim joist; On a two story home, the
rim joist is carrying the weight of the wall, the second-floor, the second-floor wall
and the roof.
