WebExample 11.4 Cylinder in Example 11.1 is made of ductile steel governed by octahedral shear-stress yield criterion (Von Mises). Determine the minimum yield stress for the steel for a factor of safety of SF = 1.75 Solution: With a factor of safety of SF = 1.75 must increase internal pressure is increased to 1.75x300 = 525 MPa. WebFactor of safety: 3. Requirement: Determine allowable soil bearing capacity using Terzaghi’s equation. Solution: From Table 1 or Figure 1, Nc = 5.7, Nq = 1.0, Nr = 0 for f = 0 degree. Determine ultimate soil bearing capacity using Terzaghi’s bearing capacity equation for square footing. Qu = 1.3 c Nc + g D Nq + 0.4 g B N g = 1.3x1000x5.7 ...
