Angle Iron Retrofits-Will they work?

By Howard Cook, Founder and General Manager of Bay Area Retrofit

Angle Iron Retrofits.

This video discusses an ineffective and untested retrofit method that your contractor or engineer may recommend.  It is always best only to use retrofit hardware and methods that are based on testing.  Otherwise, what will happen is anyone’s guess.  The information in this video was created after consultations with structural engineers Thor Matteson, Josh Kardon Ph.D, and Kelly Cobeen who was kind enough to do actual calculations as well as numerous others who were kind enough to answer questions I had about their efficacy while on a committee writing a regional retrofit guideline.  In addition, Buddy Showalter with the American Wood Council, the largest wood products research center in the world, was willing to give his expert opinion.  All of whom are highly distinguished structural engineers in the field of wood seismic retrofitting.  Calculations show that this hardware when installed perfectly has the capacity of 1/4 a standard bolt even they though they look very impressive.
