Abstract
This paper contains the fundamental outline of an experimental work developed over a period of several years covering the instrumentation and execution of horizontal load tests on bored reinforced concrete piles and pile groups. The instrumentation used is described, with particular emphasis on a system that is a completely original concept in strain measurement in piles of this kind. Hints are also given on system assemblage, insertion into the pile borehole, and preparation for automatic data acquisition. The paper also contains a description of the loading systems for piles and pile groups, giving special emphasis to the new aspects introduced. Finally, some references are made to the execution of the tests and some critical observations given on the results of the instrumentation equipment used.

Keywords:
