NUMERICAL ANALYSIS ON A BEHAVIOR OF LARGE STEEL CELL TYPE QUAY WALL DURING EARTHQUAKES

Abstract

A high seismic resistant quay wall at Yokohama Port is designed in conformity with the new technical standard for port and harbor structures revised in April 2007. The cell type quay wall is largest in the world (24.5m in diameter and 32m in height of the cell). Two-dimensional finite element analysis in effective stress is conducted for dynamic response of the quay wall. Stresses of steel cells, arcs and their joints are examined with three-dimensional static finite element analysis, in case of not only uniform but also inequable quay wall foundation.
