BASE SLIDING <br />Sliding at the base is checked at the soil -to -soil interface between the reinforced mass and the foundation <br />Forces resisting sliding = (SumVr- WO - W1 - W7) <br />6,193 - 0 - 840 - 1,000 SumVr = 4,353 ppf <br />Resisting force = SumVr x tan(32) + c x L + Base Shear Rf1 =3,284 <br />where L is the base width <br />where Base Shear = N tan(40.0) * 0.8 563.87 <br />Driving force is the horizontal component of Pah + Pqh+ Pdh Df = 1,041 <br />Factor of Safety = Rf/Df FSsl =3.36 <br />Note: Calculations and quantities are for PRELIMINARY ANALYTICAL USE ONLY and MUST NOT be used for final <br />n or construction without the independent review, verification, and approval by a qualified professional engineer. <br />CornerStone Analysis and Design 5.0.19309 <br />
