0.01-in. per second. The displacement was applied monotonically until the pile could no

longer sustain any load.

 Instrumentation

 For specimens SCC1, SCG1, SCC2 and SCG2, thirteen linear variable differential

transducers (LVDT) were placed at varying locations of the pile spans to measure the

displacement (see Fig. 6-16). The LVDTs were labeled from north to south as Dl through

D13.

 For specimens SCC1 and SCG1 foil strain gages were attached on the sides of the

piles at mid-span and on top of the pile. The strain gages at the side of the piles were

labeled from the top down as SE2 and SE3 for the east side and SW2 trough SW3 for the

west side of the pile. The longitudinal strain gage on top was labeled as Si. Specimens

SCC2 and SCG2 in addition to the longitudinal strain gages of specimens SCC1 and

SCG1 also had two longitudinal strain gages attached at the south load point (see Figs 6-

19 through 6-21) inside the contestant moment region. The two strain gages were labeled

as SSE1 and SSW1.
