F c 3000 psi fy 60 ksi natural soil development of structural design equations. A sideways force against a basement wall puts one face of the wall in tension see figure 1 next page and concrete s tensile strength is much lower than its compressive strength.

Steel is required only if the soil exerts extreme lateral pressures loads are unusually heavy the basement is built more than 8 feet below grade or there s seismic risk. Soil mechanics simplified 4. Walls generally concrete block basement walls are built without reinforcing steel. In this example the structural design of the three retaining wall components is performed by hand.

Two equations are developed. Concrete strength al ൯ne for an 10 thick wall with 5 10 and 2 5 clear to strength steel will only reduce the nominal moment capacity of the secti對on from 136 68 to 135 66 inch kips 尩 if the concrete strength decreased from 3 5 to 3 0 ksi. Building codes and retaining walls 5. Aci e702 example problems buried concrete basement wall page 3 of 9 calculations references overview of aci 318 chapter 14 walls requirements design shall satisfy sections 14 2 and 14 3 plus 14 4 14 5 or 14 8.

O section 14 2 described the general requirements o section 14 3 provides minimum reinforcement requirements. In seismic zones 2 3 and 4 ubc requires fully reinforced construction. The addition of the egress well complicates the design because obstacles outside of the foundation such as a walkway might inhibit a well s placement. Forces on retaining walls 6.
