LT$-9.$ A static load test has been conducted on a $60-$ft$.$ long, $16-$inch square precast concrete

pile that was driven from a barge through $20ft.$ of water, then $31ft.$ into the underlying soil.

Telltale rods A and B were embedded at points $30ft.$ and $59ft.$ from the top of the pile,

respectively. The data recorded at pile load failure was as follows:

Load at head of pile $=139,220lbs.$

Settlement at head of pile $=1\mathrm{.}211$ in$.$

Settlement of Telltale Rod $A=1\mathrm{.}166$ in$.$

Settlement of Telltale Rod B $=1\mathrm{.}141$ in$.$

Use the data from Telltale rod A to compute the modulus of elasticity of the concrete.

Now, use this modulus value to compute the tip bearing capacity and the side friction values

in the soil. Assume no friction exists between the Telltale Rod A embedment point and the ground

surface, so the load in the pile at depth $30ft.$ is essentially the same as that applied to the top of the

pile.
