THREE DIMENSIONAL LIQUEFACTION ANALYSIS ON A STRUCTURE ABOVE SATURATED SANDY LAYER
|
�´˜^�i‰p�j�F
A large scale shaking table test on liquefacticn behavior of on-ground stucture was perfomed to verify a 3-D dynamic effcctive stress analysis code (EFECT). This paper pimarily describes the results of the verification analysis which showed a good agreement with the experimental results on response acceleration response, time histories of excess pore water pressure and residual settlement. Secondly, the comparative analyses between 3-D and 2-D were carried out In this case, due to the predominant frequency of input motion, response acceleration of 2-D was slightly larger than that of 3-D.
