Application of Permanent Ground-Anchorage for a High-Rise Building

This paper describes the first application of permanent ground-anchorage for a highrise building. The 30 stories apartment-house has a complex architectural plan, like a flight wild geese, to reduce the influence of building shade around site. In such a case, earthquake gives strong up-lift force for column-end of specified position 1st floor and the force overtake its long term design load. Recently, permanent ground-anchorages are utilized to resist such a external force, 8 anchorages were applied to ensure the apartment-house from strong motion earthquake.
