Abstract
Stress strain relationship associated with dynamic properties of soil have been one of main subjects in earthquake engineering field. Authors developed new technique to estimate stress strain relationship of soil from shaking table test data directly. This direct estimation technique reproduces the test condition similar to the actual earthquake loading condition.
Using developed technique we successfully obtained stress strain relationship of sandy soil from centrifuge shaking table test. The dynamic properties such as a shear modulus and a damping obtained from the model test were compared with those from traditional laboratory tests. The difference between the results obtained from the centrifuge shaking table test and the traditional laboratory test is found to be substantial.
