WebNominal shear strength is controlled by masonry crushing (Equation 15), anchor pryout (Equation 16), and anchor yielding (Equation 17) and is checked as follows (as explained previously, for this example the wall geometry and direction of loading indicate shear breakout to be an unlikely failure mode): Webshear strength (Equation 12.4) is most useful. For partially, drained and undrained conditions, the evaluation of excess pore pressure is often diffi-cult. In some cases, a total-stress description of shear strength may be used. One important case is the undrained loading of saturated soils, for which the undrained shear strength (s = s) can be ...
