Abstract

The paper reviews the current state of the art on the dynamic and static analyses of RCC space frames supporting high speed centrifugal machines e.g. large turbogenerators and compressors. The need to include the effects of soil-structure interaction formulations on overall behaviour of various analytical models are highlighted, At the same time, the uncertainties involved in evaluating essential geotechnical parameters and paucity of reliable and elaborate information from the machine manufacturers are discussed. The analysis and design aspects of this inter-disciplinary problem are illustrated with two typical design case studies selected from authors’ own experience in this specialised field. The paper also discusses the usefulness, if any, of such rigorous analysis and identifies various shortcomings which still persist in finalising realistic design data and adopting suitable models to represent machine foundation-soil system.

Dynamic Response and Static Analysis of RCC Space Frames Supporting High Speed Centrifugal Machines with Coupled Soil-Structure Interaction

The paper reviews the current state of the art on the dynamic and static analyses of RCC space frames supporting high speed centrifugal machines e.g. large turbogenerators and compressors. The need to include the effects of soil-structure interaction formulations on overall behaviour of various analytical models are highlighted, At the same time, the uncertainties involved in evaluating essential geotechnical parameters and paucity of reliable and elaborate information from the machine manufacturers are discussed. The analysis and design aspects of this inter-disciplinary problem are illustrated with two typical design case studies selected from authors’ own experience in this specialised field. The paper also discusses the usefulness, if any, of such rigorous analysis and identifies various shortcomings which still persist in finalising realistic design data and adopting suitable models to represent machine foundation-soil system.
