Monitoring Of Soil Structure Interaction

Soil-structure interaction in seismic analysis

Soil-structure interaction (SSI) is an important phenomenon in the seismic response analysis. As seismologists describe seismic excitation in terms of the seismic motion of certain control point at the free surface of the initial site, the question is whether the same point of the structure (after structure appears) will have the same seismic response motion in case of the same seismic event. If yes, then seismic motion from seismologists is directly applied to the base of the structure (it is called “fixed-base analysis”), and they say that “no SSI occurs”’ (though literally speaking soil is forcing structure to move, so interaction is always present). This is a conventional approach in the field of civil engineering. However, if heavy and rigid structure (sometimes embedded) is erected on medium or soft soil site, this structure changes the seismic response motion of the soil as compared to the initial free-field picture. Such a situation is typical for Nuclear Power Plants (NPPs), deeply embedded structures, etc. The book describes different approaches to SSI analysis and different SSI effects. Special attention is paid to the Combined Asymptotic Method (CAM) developed by the author and used for the design of NPPs in seismic regions. Nowadays, some civil structures have parameters comparable to those of NPPs (e.g., masses and embedment), so these approaches become useful for the civil structural engineers as well.

Monitoring of Soil-Structure Interaction

Monitoring of Soil-Structure Interaction

This concise and authoritative work describes the equipment, methods and techniques used for measurement of soil pressure for monitoring soil-structure interaction. It is based on results of hundreds of large-scale tests and field experiments that have been conducted by Dr. Lazebnik and his colleagues in the past 30 to 40 years. The book incorporates original data and emphasizes a practical approach to developing, calibrating, and installing soil pressure measuring devices for monitoring soil-structure interaction. It offers numerous practical examples where these devices of miscellaneous designs can be used. This book is an indispensable source of information to those involved with manufacturing of soil pressure measuring instruments, investigation of soil-structure interaction phenomenon, professional geotechnical, foundation and civil engineers, and post-graduate students for their advanced studies of the subject of soil mechanics and geotechnical engineering.
