MOMENT OPTIMIZED TRUSS FOUNDATIONS FOR SINGLE-AXIS TRACKERS

摘要

A truss foundation for single-axis trackers that is optimized to resist moments. For foundations that experience lateral loads as well as moments, the foundation supports the rotational axis via a moment connection that is deliberately offset below the work point to reduce the impact of the bending moment. Spacing between the truss legs and the angle of the legs impact the height of the truss work point and, by extension, the available offset below the work point down to the minimum height of the axis of rotation specified by the tracker maker.
