A Device to Cyclic Lateral Loaded Model Piles

Model tests on small scale piles subject to cyclic lateral loading have been carried out with the purpose of simulating the pile soil behavior and its lateral resistance under environmental loads. An efficient mechanical loading system has been developed. This system is able to provide both one-way and two-way cyclic lateral loads. Frequencies and load levels in both directions can be varied in order to simulate different load conditions. There is no limitation on the number of cycles. A series of lateral cyclic loading tests for a monopile in dry sand have been carried out to demonstrate the efficiency and effectiveness of this loading system. The benefits of this innovative loading system are presented.
