RADDATZ, D  and  TAIBA, O. Modelling of a lateral load test on piles using simplified and numerical methods. J. S. Afr. Inst. Civ. Eng. [online]. 2016, vol.58, n.3, pp.13-20. ISSN 2309-8775.  http://dx.doi.org/10.17159/2309-8775/2016/v58n3a2.

The main purpose of this study was to model the response of piles during a lateral load test conducted at RPC in Concón in 2006 by using simplified theoretical methods and the software Plaxis 2D, Cype, and GGU-Latpile. The piles were the longest built in Chile at the time of the test. This article contains the test description, a geotechnical characterisation and the theoretical fundamentals that support the different methods used for modelling the test. The results of the different models are also presented here. It is concluded that results obtained by simplified methods may be efficient in the early stages of a project and that accurate approximations can be achieved by using design software for continuous elements in the design of isolated elements.

Keywords : pile; lateral load test; test modelling; finite element method; load-displacement relationship.
