100% vs 90% wood roof truss web bracing
on gable end prefabricated, light weight, metal plate connected wood roof trusses, some designers require 90% of the web height "l" braced except where it is a scissors requiring 100% (ie, notching the bracing at the top and the bottom chords). why the 100% vice the 90%?
