1976 Jrnl. Field Archaeol. 3 180 Two basic methods were considered. The first aimed at achieving structural stability through the post-tensioning of the elements. Column pieces would be connected by steel rods passing through holes drilled in their centers..and tensioned by tightening nuts on both ends of the rods.

2001 N.Y. Times (National ed.) 2 Sept. i. 21/3 The plan now is to add what architects call ‘post-tensioning’ cables to arrest the decline and possibly raise the droop up by a quarter-inch or so, but not to correct the problem any further.
