- •
Wire breakage is simulated to characterize the post-breakage behavior of a prestressing strand.
- •
The effects of modeling parameters on strand response are investigated.
- •
Breakage in an outer wire results in greater prestress loss than that in the center wire.
- •
The onset of interwire motion redistributes the load sharing among the wires.
- •
The natural frequency of strand shifts with successive wire breaks.
