Abstract: The resistance of tension rod systems can be calculated according to design codes, e.g. Eurocode 3 or DIN 18800-1. Often the real load bearing capacity is not activated by the calculated resistance – which is due to a conservative approach of the analytical design methods. The real load bearing capacity of the whole system can be evaluated by a series of ultimate load tests. The results of these tests lead to technical approvals. This procedure takes a lot of time and is very cost intensive. Therefore some European building authorities are allowing virtual tests to reduce both costs and time. A general strategy for preparing and performing virtual tests of tension rod systems is presented in this paper. Special attention is paid to generate a clear numerical model with respect to possible failure modes. The application of this strategy is illustrated by an example of virtual tests which led to a technical approval in Germany.
