  1. SOIL DESIGN REVIEW KNOWLEDGE BASE REQUIRED: STRENGTH OF MATERIALS TIMBER DESIGN SOIL MECHANICS STEEL DESIGN REVIEW OF TIMBER DESIGN • SHEAR MEMBERS • BEARING PROBLEM • BENDING MEMBERS • DEFLECTION MEMBERS • COLUMN MEMBER

  2. SOIL DESIGN REVIEW REVIEW OF SOIL MECHANICS • VERTICAL STRESSES • LATERAL STRESSES BASIC SOIL MECHANICS REVIEW: = UNIT WEIGHT OF SOIL (PCF, KN/m3) = SATURATED UNIT WEIGHT OF SOIL = BOUYANT UNIT WEIGHT OF SOIL = UNIT WEIGHT OF WATER(62.4PCF,9.81 KN/m3)

  3. SOIL DESIGN REVIEW BASIC SOIL MECHANICS REVIEW: - = VERTICAL STRESSES: = VERTICAL STRESS (PSF, TSF,KN/m2) (TOTAL STRESS) CALCULATE TOTAL Ka=0.5

  4. SOIL DESIGN REVIEW BASIC SOIL MECHANICS REVIEW: VERTICAL STRESSES at 8 feet: EFFECTIVE VERTICAL STRESSES at 8’:

  5. SOIL DESIGN REVIEW BASIC SOIL MECHANICS REVIEW: LATERAL TOTAL STRESSES at 3 feet: LATERAL STRESSES at 8 ft.(Calculating water):
