Yes, you have it right.  That's the way we design our braced frame

Subject: Concrete below base

We are designing a steel special concentric braced frame, 3 stories, in
zone 4 with rectangular concrete footings below the braced bays.  Section
1921.2.2.3 appears to require that concrete footings and tie beams be   
for ductile behavior per section 1921.  This means lap splices, closely   
ties throughout, maximum footing width per 1921.3.1.4, etc. as per   
members of concrete frames.  Is this correct or are we missing something?
