The paper describes the experimental setup used at the Institute for Geotechnical Engineering (IGS) at the University of Stuttgart to investigate the lateral load bearing behaviour of vibratory-driven steel pipe piles in dense saturated sand. The test material, the measurement devices and the experimental procedure are explained in a comprehensive manner. Afterwards the result of the pile installation and the lateral load test of one representative model test are shown and explained for one typical test in detail. The results are given in dimensionless values, i.e. a comparison with other model tests documented in literature is possible. To demonstrate the installation behaviour, the pile penetration velocity and the vertical acceleration measured at the pile head are shown. The lateral load bearing behaviour is investigated using a lateral load-displacement curve of the pile head. The experimental lateral load-displacement curve is compared with analytically determined curves using different p-y approaches. This comparison shows partially good agreement between model test and analytical solution.
