Title: Simple Equations for Tendon Failures
Author(s): Tracy M. Perry and Luis F. Estenssoro
Publication: Structural Journal
Volume: 109
Issue: 3
Appears on pages(s): 377-380
Keywords: cables; failure; post-tensioning; strands; tendons

Abstract:The corrosion of post-tensioned tendons occurs slowly. Coring through tendons, usually unintentionally, is a relatively slow process. Yet, sometimes, when tendons lose a critical amount of cross-sectional area, they fail. Tendons that fail release a large amount of energy and have been known to fly out the sides of buildings and spall their top or bottom concrete cover—sometimes in an explosive fashion. However, tendons have also been known to fail without much commotion. The purpose of this research is to study parameters that influence these different failure modes and potentially help predict other dangerous tendon failures in existing structures.
