Abstract:Numerous pull-out tests, tests on the transfer of prestressing forces, and load bearing tests on pretensioned beams made of High Performance Concrete (HPC) have been conducted. Using these tests the bond properties of 7-wire strands (dp = 0.5 in. = 12.5 mm) and ribbed wires Ø 12 mm are investigated. The lateral strain-dependent bond behavior in different types of concrete as well as the general transfer of prestressing forces are determined. Hereby, missing bases for code specifications, regulations and standards are derived for the use of bond anchorages of pretensioned tendons. The corresponding test results are presented and compared with current code specifications from Europe and the US. Furthermore, initial test results are presented concerning the influence of lateral tension and longitudinal cracks in the surrounding concrete on the anchorage of pretensioned strands.
