 BASIC STRUCTURAL SYSTEMS  

A. BEARING WALL SYSTEMS  (no frame)

1.      Light framed with shear wall

i)                    Plywood walls for structure, 3 stories or less.

ii)                  All other light frame walls

2.      Shear walls

i)                    Concrete

ii)                  Masonry

3.      Light steel framed bearing walls tension only bracing
