Information Requested
Section 4 / S4.02 illustrates the typical truSS bearing condition at the roof slab. Please note, the cast-
in"place J-Hook bolt does not lend itself to efMent constructabllity, because of the Intricate placement
required for attachment.
Recommendation
In order to provide better constructability, WELBRO suggests to utilize a powers Fastener #7250
Concrete Wedge Bolt. This 1/2" diameter x 6" (with 3" embedment depth) Concrete Wedge-Bolt has
Ultimate Strengths of 8,400 pounds in Tension and 8,730 pounds in Shear.

\ structurally acceptable.
