WebFeb 10, 2003 · Chord anchorage slip deflection values needed. thread507-45336. Cayroo (Structural) (OP) 10 Feb 03 21:23. I am trying to do an analysis of a rigid diaphragm and I am trying to find the chord anchorage slip of various holdowns and straps. The Simpson Company supplies the slip deflection value for some of their hardware, but not all. WebOct 12, 2011 · MMC Engineering. abusementpark (Structural) (OP) 11 Oct 11 23:07. Quote: You only need the full depth blocking if the shear wall is directly below the diaphragm. No full depth blocking is needed under a drag strut with no shear wall below. I'm referring to the gap between the roof diaphragm and the top plates.
