Western EWP Specifier Guide - BCI Joists

NOTE: The illustration below is showing several suggested applications for the Boise Cascade products. It is not intended to show an actual house under construction.

NO MIDSPAN BRIDGING IS REQUIRED FOR BCI'S

1 - For load bearing cantilever details, click here.
2 - VERSA-RIM 98 rim board will support 4000 lbs. per lineal foot of vertical load.
3 - BCI rim joist (where bearing length allows) will support 2000 lbs. per lineal foot of vertical load.
4 - FOR INSTALLATION STABILITY, Temporary strut lines (1x4 min.) 8" on center max. Fasten at each joist with 1-8d mails min.
5 - BCI joist blocking or 2x4 "squash" block on each side required when supporting a load-bearing wall above.
6 - VERSA-LAM header or a BCI joist header.
7 - 1 1/2" knockout holes at approximately 12" o.c. are pre-punched.
8 - See allowable hole sizes or BC CALC software.
9 - VERSA-LAM LVL beam.
10 - Endwall blocking may be required.
11 - Lateral support required when BCI joists are cantilevered. Use BCI joist blocking for at least 4 feet of every 25 feet of bearing wall length and at least 4 feet on each end of cantilevered area.

Span tables assume that sheathing is glued and nailed to joists. Spans represent the most restrictive of simple or multiple span applications. Span tables are based on a residential floor load of 40 PSF live load and 10 PSF dead load, and a clear distance between supports. Live Load deflection at L/480. Live Load deflection at L/960 to provide a floor that is much stiffer for the more discriminating purchaser. Code allowed live load deflection at L/360, see "about floor performance guide" for additional data. Span tables are based on shear values for minimum bearing lengths without web stiffeners for BCI depths of 16 inch and less. See BC CALC software for higher shear values using web stiffeners or wider bearing lengths.
