Technical Note 16 Post Tensioning

when post tensioning tendons are short One reason for this is in short tendons normal seating losses are a significant percentage of the calculated elongation Normal variations in seating losses in short tendons can often result in differences between measured and calculated elongation which fall outside the range of 177 7 tolerance permitted in ACI 318 11 Section
