GEOLAB - Centrifuge Tests on Horizontally Loaded Piles in Dry Sand - ETH Contribution to the Benchmark Project

Introduction This dataset is an output of the GEOLAB Benchmark Project and it includes measurements from geotechnical centrifuge experiments with piles in dry sand loaded laterally under monotonic and cyclic conditions. The reference (prototype) of the small-scale centrifuge models prepared by various GEOLAB members is a series of pile load tests conducted in the testing pit facility of the Technical University of Darmstadt. Objectives The objectives of the Benchmark Project was to develop of a set of best practices, which will contribute to the improvement of quality and consistency of experimental investigations across the geotechnical community. Furthermore, interesting aspects related to scale effects in reduced-scale geotechnical modelling were revealed. GEOLAB Project GEOLAB is funded by the EU’s Horizon 2020 program (Grant No. 101006512) to support research into Europe’s critical infrastructure. The project connects research installations across Europe to study the behaviour of soils and structures under realistic conditions. ETH DatasetThis dataset includes measurements from laterally loaded hollow piles in dry sand at two different scales (11.6g and 17.1g) under monotonic and cyclic loading. For each scale, measurements are available for (1) monotonic loading, (2) monotonic unloading, (3) cyclic loading of low amplitude, (4) cyclic loading of high amplitude. The measurements are scaled-up to prototype scale and include applied load, pile-head displacement and rotation, and bending moments obtained using pairs of strain gauges mounted at discrete locations along the pile. The data is available in Matrix file format (.MAT) which is the built-in format for numerical matrix data used by MATLAB.
