When possible, placing floor joist spans continuously instead of using a simply supported single span will maximize floor stiffness. Floor joist-end framing conditions were found to affect fundamental frequency, damping ratio, and span deflection through the partial restraint on joist-end rotations. Led...
Selecting TJI Floor Joist Sizes By Todd Fratzel on FramingTweetSizing Trus Joist TJI’s I’ve received dozens of emails asking me how you size TJI’s for a new home. Sizing Trus Joist brand TJI’s isn’t really that difficult once you understand the issues. Most people think that jo...
Below we give a rough "rule of thumb" that will provide a reasonable guess at allowable deck joist spans for most lumber species and grades: While it is by no means a substitute for a proper table of spans and sizes of framing lumber, home inspectors often use a quick and dirty "rule...
including both the materials and the labor. That is, if the floor joists are easily accessible, however, and if nothing else needs to be done. Additionally, the problem obviously never spans just a single square foot – at best, you’ll only need to replace a single floor joist but...
Just be aware that maximum joist spans ares complicated—they depend upon the lumber’s species and quality, and the load on the floor in addition to the joists’ sizes. If your joists are indeed too small, see some of the methods below to firm them up. How far should flooring joists ...
Subtle changes in floor usage or joist spans may also result in floor performance complaints. One common problem area is a kitchen with an island, where a homeowner may notice rattling dishes or ripples in a glass of water. A change in joist span at a bay window may also be a trouble ...
So if we applied an L/360" standard to say a floor or floor joist in which the floor spans 12 feet we can calculate (as an example) 12 ft x 12 inches per foot = 144" of total span Now 144" / 360" (L / 360") = 0.4" - telling us that 0.4" of sag below a straight horiz...

a new composite steel beam for open-web-steel-joist support; a new shear-connection-ready open-web-steel joist; and a new perimeter metal stud wall system that incorporates an in-wall wheel-stopper. The new wall systems incorporate web-perforated studs, and/or web-perforated tracks doubling ...
