Zur Krafteinleitung bei externer Vorspannung

The thesis "Transmission of Prestressing Forces of External Tendons" covers the anchorage and deviation of external prestressing tendons in hollow-box-girder bridges. At first, the behaviour of different anchorage constructions was derived from the analysis of three full-scale tests. Numerical simulations verified the results. The behaviour can be described with regular strut-and-tie-models. The derived design procedure is based on simple equations and diagrams. Further research into deviators involved geometrical aspects as well as the determination of the load-carrying behaviour. The outcome of this is a new design procedure. The third emphasis of the thesis is the analysis of the corrosion protection of external tendons at deviators. In this regard 79 tests were conducted. The basic load-bearing behaviour of anchorage and deviation constructions of external tendons results from these investigations. The derived provisions simplify previous design procedures. The tests on the corrosion protection help to understand the stress condition of external tendons at deviators. Thus, improved external tendons can be developed.
