Model Tests on Shaking Table
摘要
The ideal container is the one that gives a seismic response of the soil model identical to that obtained in the case of the prototype, i.e., the semi-infinite soil layer 1D response under vertically propagating shear waves. The boundary conditions created by the model container walls have to be considered carefully, otherwise the field conditions cannot be simulated properly. The presence of rigid and smooth end walls in the ground model introduce three serious boundary effects compared with a semi-infinite soil layer in a prototype: deformation incompatibility, stress dissimilarity and input excitation pattern dissimilarity (Carvalho et al., 2010). Bhattacharya et al. (2012) provides a review and discussion about all six different types of model container designs:
