Description
Summary:The paper presents a systematic overview of the static and dynamic analysis of turbine foundations made of reinforced concrete. It discusses the load cases to be applied, the required ultimate limit and serviceability limit state checks, the assessment of the static and dynamic foundation stiffness and special provisions required in seismic areas. Turbine foundation design is an ambitious task, requiring attention to detail and plausibility checking of all input/output parameters, as a shut down of a turbine caused by an insufficiently designed and built foundation will lead to damage that is in no proportion to its cost.
