THE DETERMINATION OF POSSIBILITY OF LOSS OF STRENGTH OF ARCH MADE OF U-SHAPE PROFILES WITH REDUCED GEOMETRICAL CHARACTERISTICS

In the scope of the paper, there were carried out calculations of highest possible load and probability of fail-safe functioning of thin sheet rolled-on profiles vault. 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.
