Устойчивость ребристых оболочек при длительных нагрузках

V.M. Zhgoutov
Stability of ribbed shells under sustained loads

The nature of creep evolution in shell material with time was analised and visually presented (changes of deflections and of stress intensity are shown). It allows to get some regularities of buckling load decrease for different reinforced concrete shells under sustained loads. It would give a possibility to design wittingly firm and stably working shell concrete structures by rational choose of their design factors.
