Intent
Intent 1: 
To limit the probability that high-strength steel tendons in concrete foundation or excavation support systems will not be resistant to corrosion or failure in bond to concrete, which could lead to loss of bearing capacity, which could lead to excessive displacement of ground, which could lead to structural failure, which could lead to harm to persons.
