Concrete Foundations For Turbine Generators

Sponsored by the Energy Division of ASCE. The design of turbine-generator foundations requires advanced technical expertise in structural engineering and soil dynamics, as well as close collaboration with manufacturers, mechanical and electrical engineers, and plant designers. Various manufacturers have different requirements for such foundations, and application of code provisions can demand a significant degree of interpretation. Concrete Foundations for Turbine Generators: Analysis, Design, and Construction provides the practical assistance needed by structural engineers and facility owners to meet these challenges with the most up-to-date and reliable information available. This Manual of Practice addresses the design of three types of concrete foundations for turbine generators: block foundations, with pedestals, piers, and blocks supported on a common mat foundation (basemat); elevated space-frame pedestal foundations, with columns, walls, and a tabletop supported on the basemat; and foundations where equipment or structural elements are supported on a vibration-isolation system. Topics include turbine generator equipment, foundation layout and sizing, foundation loads and load combinations, modeling of soil and pile response to dynamic loads, finite element modeling, serviceability analysis and acceptance criteria, strength and stability design, embedded items, vibration-isolated foundations, and construction considerations. Three appendixes on dynamic impedance discuss soil-supported rigid foundations, pile-supported foundations, and calculation examples. MOP 136 delivers state-of-the-practice guidance on turbine-generator foundations for structural design engineers, operating company personnel responsible for establishing structural design criteria and construction standards, and local building officials.

MOP 136 provides practical guidance for the analysis, design, and construction of concrete foundations for turbine generators.

The introduction of new 500 MW and 660 MW turbine generator plant in nuclear, coal- and oil-fired power stations has been partly responsible for the increase in generating capacity of the CEGB over the last 30 years. This volume provides a detailed account of experience gained in the development, design, manufacture, operation and testing of large turbine-generators in the last 20 years. With the advance in analytical and computational techniques, the application of this experience to future design and operation of large turbine-generator plant will be of great value to engineers in the industry.
