This paper examines the results of 21 full-scale field tests on minipiles and synthesises the results into a convenient design procedure that incorporates both estimated axial displacements and soil properties. Both cohesive and cohesionless soils are included in this evaluation. For all practical purposes, the developed load–displacement relationship and the geotechnical soil properties for each minipile and soil type can be used to represent the available data well through normalised average values and empirical correlations.
