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 from the analysis of a 3 x 3 pile group, as documented by Pirrello and Poulos (2014). The pile group consists of piles with a diameter of 0.5 m and an individual length of 15 m. The piles are arranged with a spacing of 2 m between each pile, both horizontally and vertically.

In this tutorial example, the use of the PileGroup program is demonstrated for analysing a pile group subject to TBM launching loading. This example involves a pile group consisting of 20 numbers of 1200 mm diameter CFA piles of 20 m long, which were spaced at three pile diameters in both directions.

This blog documents a case study for laterally loaded piles in soils with both cohesion and friction (c-phi soils) using the PileLAT program

We are pleased to announce that PileLAT Version 2.3.1 has been released with the following improvements and updates.

P-y curve model for weak carbonate rock proposed by Abbs (1983)

PileLAT program adopts the p-y curve model of liquefied sand recommended in Rollins (2005) based on the full-scale lateral load tests.

This blog explains how to start a new analysis for laterally loaded single piles using the PileLAT program. Step by step, it demonstrates how to (1) Define pile section and length, (2) Create p-y curve model, (3) Define ground profile, (4) Apply pile head loads, (5) Run the analysis, and (6) View the analysis results.

This blog presents a case study with using PileLAT program for a pile lateral load test carried out in Salt Lake City in 2003. Figure 1...
