ABSTRACT
Standard procedures concerning axial and lateral capacity testing of foundation piles usually consist of a single loading cycle. Constant load steps or constant settlement increments may be applied in the test. Such a procedure significantly differs from in-situ conditions of pile loading, witch can be cyclic – especially in the case of the constructions, which are subject to wind load. Several tests were performed to observe the behavior of the driven piles subject to fast cyclic loading in horizontal direction (lateral load). The piles were originally designed for the foundation of noise barriers along the highway. Some of the piles were broken in course of driving and a cautious check of their behavior under load was requested before the assembling of the entire structure. The research conducted at Wroclaw University of Technology made it possible to collect and summarize the results of displacement measurements in course of static load testing of driven piles. Some selected case studies of cyclic loading in horizontal (lateral) pile load tests were presented in the paper.
