moment. Selection of a foundation design depends on the turbine location and site conditions. Onshore turbines typically use reinforced concrete slab or multi-pile type designs. Examples of these foundations are described by Burton et al. (2001). The dimensions of slab foundations for large onshore turbines depend on the geotechnical

The first codes and regulations for the design of reinforced concrete structures were published in the UK in the 1920s and 1930s, by which time concrete became one of the most widely used construction materials. The development of prestressing, largely by Freysinnet in the 1930s, saw the construction of ever more elegant and slender structures ...
