Hello all,
I have had a number of design projects recently where I have had to design foundation to resist significant overturning forces from moment frames.
While trying to design the footings for the lateral resisting members, I was running into an issue where my software (RisaFoundation and...

I want to reject the submittal because it clearly does not meet the ASTM we provide...
