PileGroup Validation - Example 10. Full scale static lateral load test of a 3x4 pile group in clay (Rollins et al. 2003)

PileGroup Validation - Example 9. Full scale static lateral load test of a 3x3 pile group in clay (Rollins et al. 2003)

This example is based on the centrifuge lateral load test of a 2 × 2 pile group founded in soft clay reported by Taghavi et al. (2014). The piles in the groups were spaced at 7.0 pile diameters and had a 2×2 symmetrical configuration in plan and were fixed to a rigid cap placed above the ground level. The model pile was fabricated from a hollow steel tube instrumented with six pairs of strain gauges at different levels to enable bending moment measurements along the pile.

PileGroup Validation - Example 7. Centrifuge lateral load test of a 3x4 pile group in loose sand (Zhang et al. 1999)

This example is based on the full-scale lateral load test of a 3 × 5 pile group reported by Walsh (2005). The test site comprised alternating sand and clay layers. The piles were steel pipes with an outer diameter of 0.324 m and a wall thickness of 0.0095 m. In the direction of loading, the piles were spaced at 3.92D (1.27 m) centre-to-centre, and 3.29D (1.07 m) centre-to-centre perpendicular to the loading direction. Each pile had an embedded length of 16.6 m, with the groun

This example is based on the full-scale lateral load test of a 3 × 3 pile group reported by Rollins et al. (2005). The piles were spaced at 3.3 diameters centre-to-centre and were driven open-ended into a soil profile consisting of loose to medium-dense sand underlain by clay. Each pile was a steel pipe with an external diameter of 0.324 m and a wall thickness of 9.5 mm, driven to a depth of approximately 11.5 m below the excavated ground surface.

This example is based on the full-scale lateral load test of a 3 × 3 pile group reported by Christensen (2006). The test site comprised alternating sand and clay layers. The piles were steel pipes with an outer diameter of 0.324 m and a wall thickness of 0.0095 m. In the direction of loading, the piles were spaced at 5.65D (1.83 m) centre-to-centre, and 3.29D (1.07 m) centre-to-centre perpendicular to the loading direction. Each pile had an embedded length of 12.8 m, with the
