steel floor joists span tables

New girderheader tables have been revised to incorporate the use of 2 Southern Pine in lieu of 1 Southern Pine. Other span tables are based on the guidance given in BS 5268-71 which is a uniformly distributed load of 15kNm² for spans greater than 2400 mm and 36 kN load per metre width of floor for spans less than 2400 mm to ensure that very small joist sizes do not result from the calculations for smaller spans.

Lets expand our house beyond that 172 span capability to 24 feet wide.

. These concentrated loads often include standard steel joists that are in turn supporting steel roof or floor deck. Structural steel is commonly used in basements since they are height adjustable to accommodate any. Allowing for seamless integration of mechanical electrical and plumbing MEP systems.

Using a composite joist narrows the floor creating more headroom often with adequate MEP routing options through the joist. With the allowable cantilever of the joists this beam would support a deck 12 feet by 17 12 feet. Joists can also be spaced farther apart translating to reductions in steel manufacturing shipping and erection costs.

New tables address alternative wood stud heights and the required number of full height studs in high wind areas. Also shear studs increase joist strength thereby expanding the span-to-depth ratio limit to 30 times. The exemption for interconnection of smoke alarms in existing areas has been deleted.

Other span tables are based on the guidance given in BS 5268-71 which is a uniformly distributed load of 15kNm² for spans greater than 2400 mm and 36 kN load per metre width of floor for spans less than 2400 mm to ensure that very small joist sizes do not result from the calculations for smaller spans. The open-web design of steel joists and joist girders introduce a range of cost and performance advantages. A southern pine 2 2x12 beam can span 8 feet when supporting joists spanning a maximum of 14 feet and it can cantilever 2 feet beyond the posts on each side.

The widest span in the floor joist span table in Part 2 of this tutorial module showed that floor joists can span 172 if they are 2 X 12s spaced 12 oc.
