How To Install Rim Joists
The direction floor joists run is determined by the architect or engineer. In general, floor joists run front to back on a rectangular house which is the shortest possible way. Architects try to keep the floor joists as short as possible to prevent flexing. The longer the span, the bigger the joists need to be.

What are joists made of?
Joists are mostly made from timber, reinforced concrete, or steel and are usually laid in parallel under a roof or floor. In almost all construction projects, joists are laid together in large numbers to provide sufficient secondary support.
Why do joists need beams?
Joists rely on beams as their central support in both light and massive construction projects. This is because joists can either be placed on or beside beams to allow for the proper and efficient load transfer. To support joists and accommodate the load, beams are usually supported by columns.
What are the different types of beams?
Below are some of the main types of beams: 1 Steel beams: Steel beams are stronger and more expensive than wood beams. You’ll find steel beams in large buildings and tall structures. Wood beams are common in small projects such as home construction. 2 Combined Dimensional Lumber: Combined beams are stronger compared to standard wooden beams. This is because combined beams are made when several pieces of dimensional lumber are joined to form a stronger, longer beam. 3 Flitch Beams: Flitch beams are a unique type of beam in that they make use of a steel sheet that’s sandwiched between two sets of dimensional lumber. The steel reinforces the beams, making the structure stronger and more capable of withstanding weight pressure. The dimensional lumbers that sandwich the steel help to prevent flexing, thus keeping the beam in good shape to function long term. 4 Engineered Beams: Engineered beams are modified to provide deeper and stronger load transfer. They are mostly known for their I-shaped cross-sections. Engineered beams often make use of plywood, which allows for customization to almost any desired depth.
What is the difference between a girder and a joist?
The main differences between joists, beams, and girders are size, design, and functionality . Joists are usually small but numerous and mostly supported by beams. Compared to joists, beams are larger and fewer. Girders are the largest of the three and provide the primary horizontal support to beams.
Why are beams larger than joists?
Compared to joists, beams are larger in size to enable proper load transfer to the columns and foundation. Beams run horizontally across the ceiling or floors and play a huge role in the structural integrity of a building.
How do beams work?
But beams function in a similar manner to girders in that they provide structural support by transferring the load to the columns. Beams are common in residential structures, often found in walls, floors, ceilings, decks, and roofs. In a large construction project, beams play the role of secondary support.
Why are joists more important in a ceiling?
Generally, the larger the construction work, the more the joists needed for stability. Therefore, in a structure, joists will be more due to their small sizes. Since joists have small cross-sections, they are usually aligned in large numbers across the load to absorb and transfer the weight to the beam.
