Wind turbine tower is a typical high-rise structure building.. The average wind tower height on earth is around 90m – 130m. The wind turbine foundation bears the load transmitted from the wind turbine tower and the turbine on the top, especially the huge overturning moments.. For onshore wind turbine tower, there are basically 5 common types of wind …

Pile Supported Foundation (Pile Cap) Analysis and Design Based on a geotechnical study, a pile supported foundation is required to support a heavily loaded building column. Design the pile cap shown in the following figure with 12 in. diameter piles and a service load capacity of 50 tons each.
the model considers also the major effects of mill body, foundation and soil. The mill is modeled as a rigid body. Spring elements at the center of the mill consider the stiff-ness of the mill and its bearings. The simplified foundation is modeled by volume elements and considers the weak-ness of foundation and soil.
