4.2 WOODFRAME FLOOR SYSTEMS Woodframe floors typically consist of repetitive joists or trusses, at a prescribed spacing, sheathed with either boards or wood structural panels attached to the top surface. Finish materials such as gypsum board typically are applied to the bottom surface where it serves as the ceiling for a room below.

Understanding Loads and Using Span Tables -

For example: a floor joist appropriately selected to span 10 feet with an L/360 limit will deflect no more than 120"/360 = 1/3 inches under maximum design loads. Drywall attached to the underside of this system is not expected to crack when the floor joist system deflects 1/3".

The Design of Reinforced Concrete Slabs

Selecting the most effective floor system can be vital to achieving overall economy, especially for low- and mid-rise buildings and for buildings subjected to relatively low lateral forces where the cost of the lateral-force-resisting system is minimal.

Floor Truss Buying Guide at Menards

A floor truss is a system that supports the weight of a building. Similarly, an I-joist functions as a support system for various structures. However, there are numerous differences between floor trusses and I-joists.

The depth of a floor system is directly related to the size and proportion of the structural bays it must span and the strength of the materials used. The size and placement of any cantilevers and openings within the floor plane should also be considered in the layout of the structural supports for the floor.

Floor Systems - Deflection and Vibration - Floor Vibration 2

As machine stress-rated (MSR) lumber becomes easier to obtain, it may be specified for floor systems. Using MSR joists instead of S-P-F will result in an increase of about 9% in the allowable vibration-controlled span. Glue subfloor and/or use thicker panels. The floor joists and the subfloor act as a system.

Floor Truss Buying Guide at Menards

Floor trusses can span farther between bearing points than I-joists, allowing for larger open rooms. This also reduces the need and cost for extra bearing posts, beams, and footings. Floor trusses have built-in openings, which can be used to install HVAC ductwork, plumbing lines, and electrical wiring.
