A ground anchor has two forms of capacity, a geotechnical and a structural resistance. The structural resistance of the tendons is defined by EC steel standards while the bonded zone has to be examined for its pull-out capacity (geotechnical check). The new software includes a number of ground anchor (tieback) sections.
