INTEGRAL ACTION OF THE SOIL-FOUNDATION-SUPERSTRUCTURE SYSTEM |
|
|
|
|
As discussed previously, in order to obtain good performance of structures during severe seismic ground shaking it is necessary to analyze thoroughly the dynamic characteristics of the real three-dimensional soil-foundation (substructure)-superstructure system. Except for the cases where base isolation techniques and/or energy dissipation devices are used, the basic rule for earthquake-resistant design is to achieve integral action of each of the main parts of the system and between these main parts, that is, the whole substructure and superstructure should be tied together so that they can work as a unit (Slides J19-J21). |
