Steel Elements of Structural Wall Anchorage
(OP)
ASCE7 Section 12.11.2.2.2 say that the strength design forces of all steel elements in an achorage system need to be increased by 1.4. I'm working on a project with a wood roof and diaphragm and am using Simpson straps to satisfy the anchorage forces. It seems pretty clear to me that I need to increase these forcesd by 1.4, but I have had other people tell me that only counts for an anchorager system that is entirely made of steel. I'm a little dubious about that argument but thought I'd throw it out there and see what others thought.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

Woodman -- I believe the factors you are quoting are for the conversion from ASD to LRFD. For seismic it is 1/0.7 = 1.43 ~ 1.4, and for wind it is 1.6.
