Seismic finite element simulation of concrete piles in harbour landing stages
Seven reduced-scale prestressed concrete (PC) pile specimens for landing stages simulating four levels of corrosion were tested to investigate their structural cyclic lateral load-carrying behaviour. Three corroded specimens were repaired using fiber-reinforced polymer (FRP) jacketing before testing. In this paper, the force-based fibre element (FFE) and the OpenSees software are used to analyse the seven PC pile specimens, achieving good corroboration with tests. Because the corrosion in such piles is horizontally asymmetric, the validated FFE models are used to execute 78 pushover analyses along various lateral directions to determine the multi-directional lateral strengths of the six corroded specimens. Based on the FFE analyses and experimental observations, this study makes design recommendations for FRP jacketing for use in repairing corroded landing stage PC piles. The FFE modelling is also extended to simulate the entire pile–soil system of an in situ pile lateral load test, validating its feasibility and accuracy for an entire full-size pile–soil system.
