Question

A 250 mm square, 15mm long prestressed concrete pile (fc = 40 mpa) was driven at a site in Amsterdam as described by Heijnen and Janse. A conventional load test conducted 31 days later produced the load -settlement curve shown in figure. Using Davisson's method, compute the ultimate load capacity of this pile 

A 250 mm square, 15 m long prestressed concrete pile (fc = 40 MPa) was driven at a site in Amsterdam as described by
Heijnen and Janse (1985). A conventional load test conducted 31 days later produced the load-settlement curve shown in
Figure. Using Davisson method, compute the nominal axial downward load capacity of this pile.
