Cantilever Retaining Wall, Pressure Relief Shelf, SAP-2000, Depth Ratio (h/H)

The Concept of providing pressure relief shelves on the backfill side of a retaining wall reduces the total earth pressure on the wall, due to which it reduces the thickness of the wall and ultimately gives more economical design. In the present study an attempt is made to analyse the cantilever retaining wall with pressure relief shelf by using finite element package (SAP-2000). Springs are assigned by discretising the model to simulate soil properties. The model is validated from the standard book. Using SAP-2000 optimized position of relief shelf is concluded for the single shelf cantilever retaining wall by considering top displacement of the wall and the maximum bending moment in stem and shelf, using those results further studies can be made for economy of the structure.
