Abstract

Some centrifugal shaking tests were carried out to clarify the mechanism of seismic interaction between a large caisson foundation and soil layers. Based on the test data, two-dimensional seismic effective stress FE analysis was applied, followed by verifying its applicability. Also, to clarify the flexural and shear behavior of the caisson structure members to the ultimate state and to evaluate the flexural and shear resistance, some large-scale model failure tests of poorly reinforced concrete in caisson foundation were carried out. Based on these test results above-mentioned, seismic analyses of an existing large caisson foundation to ground motion in level 2 earthquakes were carried out, adopting the above-mentioned analysis. As the results, it was concluded that the seismic safety on the caisson foundation was confirmed.

Evaluation of Seismic Safety of a Large Caisson Structure

San Diego, California

Some centrifugal shaking tests were carried out to clarify the mechanism of seismic interaction between a large caisson foundation and soil layers. Based on the test data, two-dimensional seismic effective stress FE analysis was applied, followed by verifying its applicability. Also, to clarify the flexural and shear behavior of the caisson structure members to the ultimate state and to evaluate the flexural and shear resistance, some large-scale model failure tests of poorly reinforced concrete in caisson foundation were carried out. Based on these test results above-mentioned, seismic analyses of an existing large caisson foundation to ground motion in level 2 earthquakes were carried out, adopting the above-mentioned analysis.
