The simply supported reinforced concrete plate was taken as an example. The plate was loaded by uniformly distributed loads. Several parameters that influence the plate deflection are given as certain closed intervals. Accordingly, the results are obtained as intervals so it was possible to follow the direct influence of a change of one or more input parameters on output (in our example, deflection) values by using one model and one computing procedure. The described procedure could be applied to any FEM calculation in order to keep calculation tolerances, ISO-tolerances, and production tolerances in close limits (admissible limits). The Wolfram Mathematica has been used as tool for interval calculation. 4950 https://doi.org/10.25643/bauhaus-universitaet.2839$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:wim2-20170314-28397$xR$3Volltext$534 4961 https://www.db-thueringen.de/receive/dbt_mods_00037082 5051 000 5051 510 5550 Angewandte Informatik 5550 Angewandte Mathematik 5550 Architektur 5550 Computerunterstütztes Verfahren
