Abstract | Fibre composites in deep foundation industry have been recognized to replace conventional materials such as concrete, steel and timber in harsh marine environment. The emergence of hollow fibre reinforced polymer (FRP) composite tubes as a structural component provided the industry to consider this material as a potential composite pile type as they can carry design load. However, issue such as driving performance of this material warrants investigation as they are considered the lowest performer among composite piles. The thin-walled section generally ruptures under high driving stresses, thus its stiffness for post-impact performance is in question. This paper experimentally investigated the effects of impact energy and number of impacts on the axial stiffness of hollow FRP composite tubes. Six incident energy variants were considered, and two specimens for a given impact energy were subjected to a maximum of 130 repeated impacts using a drop-weight impact tester. The impact response and the contact stiffness were evaluated in terms of damage |
