A PARAMETRIC STUDY OF SEISMIC COEFFICINETS FOR SHEET PILE QUAY WALLS AT FISHING PORTS

Abstract

 Until now, seismic-resistant design of sheet pile quay walls at fishing ports has been done with seismic coefficients table which roughly consider area classification and ground characteristics. However, those coefficients do not reflect seismic behavior of soil and walls. On the other hand, sheet pile quay walls in deep water depth at commercial or industrial ports are now designed using a new coefficient and its calculation method which reflects seismic behavior and allowable deformation amount.

 This paper aimed at an application of new coefficient and its calculation method for sheet pile quay walls in shallow water depth at fishing ports. For that reason, two-dimensional seismic analysis is carried out to identify the parameters for calculating seismic coefficients suitable for water depth of quay walls at fishing ports and its standard design method. On the premise of application of a new method, stress characteristics of structural members are also verified.
