The actuality of the research is caused by comprehensive study' insufficiency of thin sheet rolled-on U-form profiles vault's functioning reliability. The theoretical and methodological bases of the research are the theories of highest normal tensions and maximum strained conditions as well. In the course of the probability of the construction strength's failure's research there were applied modern software tools' means as Lira and SolidWorks. The results are the values of the highest possible thin sheet rolled-on profiles vault with reduced geometry features load and initial construction reliability. Results earned enabled to make a conclusion of insufficient vault's reliability.reliabilityrolled-on metal thin-sheet profilesreduced geometry features loadhighest possible loadmathematical expectationstandard deviationcomputer modeling1.ТУ 5262-144-02494680-2004.
