In this study, the seismic vulnerability of a pile-supported wharf is assessed. Due to common lack of empirical data, the analytical fragility curves are developed using the results of the dynamic analysis of wharf subjected to the different time histories. Fragility curves are developed considering three engineering demand parameters, including displacement ductility factor (m d ), differential settlement between deck and behind land and normalised residual horizontal displacement (NRHD). A sensitivity analysis using both the first-order second-moment method and the tornado diagram analysis is then carried out to evaluate the effects of uncertainties associated with geotechnical parameters in the seismic performance of the wharf. Adopted fragility curves are useful to seismic risk assessment. They can also be used to optimise wharf-retrofit methods. The results of sensitivity analysis demonstrate that uncertainties associated with the permeability of hydraulic placed sand fill contribute most to the variance of both NRHD and m d . While in the case of differential settlement, the friction angle of rock fill contributes most to the variance.

“…Numerous studies have been dedicated to examining the seismic behavior of wharves. For instance, Dodds et al (2004) (Dodds et al, 2004) utilized elastic-perfectly plastic models to assess the seismic stability of the Kings Wharf in Suva, Fiji, incorporating site soil materials and piles. Similarly, Smith et al (2004) (Smith et al, 2004) adopted a comparable modeling approach to evaluate a novel design for a wharf at the Port of Vancouver in British Columbia.…”

The article presents a comprehensive investigation into the design intricacies of quays in coastal regions, with a specific focus on open-type and closed-type quay structures. The study acknowledges the strategic importance of ports in such areas and their vulnerability to seismic and hydrodynamic forces. By synthesizing insights from diverse research endeavors related to the seismic behavior of wharves, the article elucidates the methodologies employed to assess stability and performance. The research is centered around Chamkhaleh Port and underscores the significance of innovative design strategies, especially in light of the vulnerabilities observed at the nearby Bandar Anzali port. The article meticulously analyzes design considerations, load distribution mechanisms, and cost-efficiency aspects, particularly in relation to pile diameters and lengths. The findings highlight the necessity of tailored design approaches to ensure the structural robustness of quays and to mitigate risks arising from various forces. The research not only offers valuable insights to engineers and stakeholders engaged in port infrastructure development but also advocates for safety, sustainability, and cost-effectiveness in the realm of port design and construction.

Seismic Performance of Pile-Supported Wharf Structures considering Soil-Structure Interaction in Liquefied Soil

et al. 2012

Many existing pile-supported marginal wharves within ports along the West Coast of the United States were designed in the late 1960s and early 1970s using the seismic design criteria available then, which were much less robust than the current criteria. As a result, structures designed using these criteria have often been severely damaged during the past earthquakes. This paper investigates the modal properties and vulnerability of such structures by using advanced structural and soil modeling procedures to perform two-dimensional nonlinear plane-strain seismic analyses using time histories of ground displacement and excess pore water pressures within the underlying soil embankment. Results show that the wharf structure experiences large permanent deformations and undergoes failure of the piles and pile-deck connections and pullout of batter piles in tension under large seismic events. Such failures were observed at the Port of Oakland during the 1989 Loma Prieta earthquake and also during other earthquakes throughout the world.
