2. Benchmark solution#

2.1. Calculation method#

The reference values are obtained by comparison with EUROPLEXUS for modeling A. For models B and C, the reference values are non-regression.

The reference results for modeling A are summarized in the following table. The data are obtained at point \({P}_{04}\) (cf. figure 3.1-a).
