Abstract
Dynamic behavior of a large scale steel cellular bulkhead was investigated by centrifugal model test and simulation analysis by both two-dimensional model and 3-dimensional model. The bulkhead moved toward front side with settlement and inclination and the bulkhead showed the behavior as the rigid body. However the cell and the arc showed complicated behavior as to both vertical direction and circumferential direction. The simulation results were fairly good agreement with the test results as to its movement. However the shearing deformation of filled sand in the cellular was overestimated by 2-dimensional model whereas the large Mises' stress was calculated by 3-dimensional analysis. The calculation results by current design method gave safety side results but the complicated stress behavior on the cellular was not estimated by current design method.
