Closure to 'Load and Resistance Factor Design of Drilled Shafts in Sand' by D. Basu and Rodrigo Salgado

摘要

The main points in the discussion by Bengt H. Fellenius seem to be related to the following: 1. Choice of the load at 10% relative settlement as the ultimate pile load capacity; 2. Existence of the limit pile base resistance; and 3. The shaft capacity equation and the variables involved in that equation. Each of the previous points are addressed, but in a different sequence. Point 2 will be addressed first, followed by points 1 and 3.
