Abstract
Laterally loaded pile foundations are more commonly employed in geotechnical engineering due to their widespread utilisation in contemporary construction projects, with examples including wind turbines. The most effective method for estimating pile lateral capacity is a static load test conducted in a natural scale. However, there are some challenges associated with field performance tests, which can be avoided by conducting them on model piles in a laboratory scale. This article presents the initial results from a series of lateral static load tests conducted on steel pipe piles in a laboratory scale. Based on the retrieved results, an analysis of the loaddisplacement pile lateral behaviour was performed, and the pile lateral bearing capacities were estimated with approximation methods. In addition, an approximation error analysis was performed.
