Abstract:The Maurer-Normanker, proved now for 15 years of service, and the new designed Robek-Zahnanker have practically the same high level of quality. However, the new designed Robek- Zahnstegfuge showed far the best results in this dynamic load test. The reason is firstly the fact that the anchor system is incorporated into the profile without the need of any welding eliminating the concern for fatigue failure. And secondly, it was obvious during the dynamic tests that the slim section of the upper profile was working like a leaf spring, so only a reduced load went down to the anchoring system. This surprising result with the Robek- Zahnstegfuge of the laboratory tests in 1978 gives an interesting outlook for further design practices.
