R403.1.2 Continuous footing in Seismic Design Categories D0, D1 and D2
JUMP TO FULL CODE CHAPTER
Exterior walls of buildings located in
Seismic Design Categories D0, D1 and D2 shall be supported
by continuous solid or fully grouted masonry or concrete
footings. Other footing materials or systems shall be
designed in accordance with accepted engineering practice.
All required interior braced wall panels in buildings located
in Seismic Design Categories D0, D1 and D2 with plan
dimensions greater than 50 feet (15240 mm) shall be supported
by continuous solid or fully grouted masonry or concrete
footings in accordance with Section R403.1.3.4,
except for two-story buildings in Seismic Design Category
D2, in which all braced wall panels, interior and exterior,
shall be supported on continuous foundations.
Exception: Two-story buildings shall be permitted to
have interior braced wall panels supported on continuous
foundations at intervals not exceeding 50 feet (15240 mm) provided that:
- The height of cripple walls does not exceed 4 feet (1219 mm).
- First-floor braced wall panels are supported on doubled floor joists, continuous blocking or floor beams.
- The distance between bracing lines does not exceed twice the building width measured parallel to the braced wall line.
