Notes:
User to verify site specific Equivalent Fluid Pressure for
backfill material.
Moment Magnifier method used, UBC 1910.11. Meets design requirements
of CABO 304.3 and 304.4. Required reinforcing very sensitive to
eccentric loading, table based on concentric loading (e=0). Axial
Loads are maximum allowable for given reinforcing. Reinforcing CANNOT
be reduced for non-bearing application at tabulated backfill height.
Reinforcing bar to be placed in the center of the wall. Seismic Zones
3 & 4 use maximum vertical spacing of 12" with equivalent steel,
and 2 #4 horizontal in the top beam.
