“…In this regard, the definition of k h could be further improved in future studies. In addition, the influence of excess pore water pressure developed in the backfill during earthquake should be evaluated for port structures (Zeng & Steedman, 1993;Iai et al, 1998;Kim et al, 2005;Lee, 2005).…”

In the simplified analysis of seismic design of gravity quay walls based on the pseudo-static approach, selection of an appropriate horizontal seismic coefficient (k h ) is important for computing the equivalent pseudo-static inertial force. However, there is no unified standard for defining k h . There are conflicts among the existing k h definitions regarding whether it considers (a) the effect of wall height on maximum horizontal acceleration (MHA) used in the determination of k h or (b) the application of correction factor for k h according to seismic performance grade. This paper evaluates the relevance of these conflicts by initially reviewing the k h definitions in the existing codes and guidelines for port structures and then by performing a series of dynamic centrifuge tests on caisson gravity quay walls of different wall heights (5, 10 and 15 m). A review of the existing codes and guidelines has shown that the correction factor for k h should be specified according to the seismic performance grade for the economical design of quay walls. On the other hand, based on the centrifuge tests, it was found that the MHA used in k h calculation and the correction factor for considering seismic performance grade should reflect the effect of wall height.

“…Soil liquefaction is known to be one of the most severe seismic hazards, causing damage to structures founded on both shallow and deep foundations, harbor structures, and disrupting buried infrastructure such as communication lines [1][2][3]. In engineering practice, it is essential to identify those sites vulnerable to liquefaction-induced damage and to then mitigate possible damage by taking appropriate measures in advance of a seismic event.…”

“…Although the design procedure for gravity quay walls is reasonably well established for static loads, their analysis under seismic loads requires further investigation. This fact was revealed after occurrence of severe damages to the waterfront structures in earthquakes such as Kobe, Japan (Ishihara, 1997) and Chi-Chi, Taiwan (Lee, 2005).…”
