Seismic vertical uplift capacity of strip anchors

Anchors are employed in the foundations of structures such as transmission towers, dry docks and buried pipelines under water. Considerable literature is available to estimate the failure loads of anchors to resist static uplift forces Meyerhof & Adams, 1968; Rowe & Davis, 1982; Murray & Geddes, 1987; Subba Rao & Kumar, 1994. However, hardly any information is available to compute the uplift capacity of anchors during the occurrence of an earthquake. In the present note, the influence of horizontal earthquake acceleration on the vertical uplift capacity of shallow strip anchors buried in cohesionless material has been theoretically examined by...
