DESIGN AND DETAILING OF RETAINING WALLS

Design of Shear key: If the wall is not safe against sliding, then a shear key is to be provided. It is provided either below the stem or at the end of heel. It should not be provided at the end of toe. If shear key is provided, then it should be designed taking the effect of passive pressure.

Beam Bending Stresses and Shear Stress

Even vertical connectors have shear flow across them. The spacing can be determined by the capacity in shear of the connector(s) to the shear flow over the spacing interval, p. Unsymmetrical Sections or Shear If the section is not symmetric, or has a shear not in that plane, the member can bend and twist. If the load is applied at the shear center
