The Technische Universität München (Technical University Munich) has carried out many static and dynamic tests. The following results, which are based on the production version of the bearer, are available:
Target: 2 million load changes at a load of 35 kN
2 bearers were subjected to 2.16 million and 2.18 million load changes respectively, while a third bearer was to be stressed until it failed. The test was finally terminated at 6.34 million cycles, since no changes could be observed.
Afterwards, the three prestressed bearers, as well as a new bearer were subjected to a static test. The bearer, which was prestressed with 6.34 million cycles, broke at a static load of 197 kN. All other bearers exceeded the testing machine’s maximum power of 200 kN.
