...Abstract Post-tensioning (PT) has evolved to become an important technology for affecting integrity of bridge structures. However, tendon failures resulting from wire/strand corrosion have been reported within two years of construction. In response to this, a recent study introduced and evaluated...

... ( CR ) , and (3 T f (tendon  ) = 1.44 / μ ( CR ) . Abstract Post-tensioning (PT) has become an important technology for affecting integrity of large reinforced concrete structures, including bridges. While there are a number of advantages to PT construction compared...

...Abstract Post-tensioned (PT) concrete construction was first introduced over 60 years ago and has evolved to become a prime methodology for affecting integrity of large reinforced concrete structures, including bridges. While there are a number of advantages to PT construction compared...

... post-tensioning has evolved to become the construction method of choice for many structures, including bridges. However, instances of corrosion induced fracture of wires and strands and failure of tendons have occurred as a consequence of either chemically or physically deficient grout...

...Abstract A forensic investigation of unbonded post-tensioning (PT) tendons on a large structure revealed relatively advanced levels of strand corrosion within and inboard of anchors. In addition to concerns that this corrosion could result in wire and strand fractures and, hence, tendon failures...

.... It was simply assumed that only the outer surface of the strands bundle in Figure 5(c) was electrochemically significant. Thus, an effective diameter of this equivalent was calculated from the total nominal cross section area of 19 0.6"- post-tensioning strands. A small 2 cm-long segment on the top...

... of the balconies tested, a corrosion rate measurement was also made on the railing anchors. All the measured corrosion rates were relatively low. Abstract Two case studies dealing with the deterioration of conventionally reinforced and post-tensioned concrete balconies due to reinforcing steel corrosion...
