When this type of connection fails, ie. moves but does not shear the bolt off, does my now bearing connection increase in shear capacity (Fv). Example; a 3/4" A325-SC has the shear capacity of 7.51k (ASD). When the connection moves and changes to a full bearing condition, does my shear capacity increase to 9.3k for A325-N or am I still held to the SC value?
Now say if a contractor installs A325 TS (twist-off-type control bolt assemblies) bolts (Pre-tension to 70% per Table J3.7 w/ out surface preparation) when I only specified A325-N connections, do I take a shear reduction because of the combined stresses?

Product engineers and tooling manufacturers have much to gain from 3D printing: By generating low-cost physical prototypes early in the design process, they can check form, fit and function, gauge customer response and compare design iterations without commitment. Download Now
