Abstract
Geotechnical earthquake engineering problems and similar soil dynamics problems usually involve random three directional cyclic loads, complicated stratification of soil deposits and geometry of supported structures, heterogeneity, anisotropy, and nonlinearity of soils, large degradation of soil stiffness and strength accompanied by equally large displacements and deformations, complex interaction between different soil deposits and between the foundation soil and the supported structure, etc. On the other hand, the empirical and analytical methods used in conjunction with standard field testing or standard laboratory cyclic testing on small specimens, which are currently available in engineering practice, are relatively simple and limited to ideal conditions. In most cases, such methods can provide only a rough estimate of the response of a foundation-structure system to seismic or similar cyclic loads. Consequently, large scale field and laboratory testing, testing of soil-structure models using shaking table, and centrifuge testing play an important role in the advancement of soil dynamics design methods. Such testing, however, in comparison with standard experimental and analytical soil dynamics investigations, is quite expensive. It requires special facilities with an adequate technical support and it involves team work. The affiliations of the authors in this session, as well as the number of the authors of some papers, show that such complex and expensive studies are done mainly by large corporations or large institutes in cooperation with universities.
