Abstract
Deep rectangular barrettes are frequently used in tower foundations to resist large axial and substantial horizontal loads. Bi-directional static load tests are widely used as an axial capacity evaluation tool in safe foundation design. This paper articulates the results of a barrette test of 2.80 × 0.80 m in size in the multi-layered soil of Georgia. The maximum applied bidirectional load of 50-m-deep strain gauge instrumented barrette was 51,670 kN. The results indicate a settlement of 8.90 mm at the working load of 25,835 kN and 34.50 mm at the ultimate test load. The shaft resistance and settlement analyses were carried out to understand the geotechnical performance of the barrette in the layered soil. This investigation contributed to a significant, reliable result for the design of the rectangular barrette in multi-layered soil with substantial cost and time savings.
