erformed experiments on additionally strengthened vaults with metallic helical reinforcement and non-metallic composite glass reinforcement (GFRP) proved expressive influence on carrying – capacity of masonry vaults. These experiments were nevertheless carried out on vaults without backfill. The question then is, what kind of interaction takes place between non-strengthened or strengthened vault with backfill. Realization of experiments in real conditions would be technically and financially very difficult, and therefore cooperation of vaults in combination with backfill has been simulated in computational programme Atena based on earlier performed experiments

Badania wykonane na sklepieniach wzmocnionych śrubowym zbrojeniem stalowym i szklanym zbrojeniem kompozytowym (GFRP) potwierdziły wyraźny wpływ na nośność sklepień ceglanych. Badania te zostały wykonane na sklepieniach bez nadbudowy. Zachodzi zatem pytanie, jaka jest współpraca sklepienia wzmocnionego oraz sklepienia bez wzmocnienia z nadbudową? Realizacja takich badań byłaby technicznie i finansowo bardzo trudna, stąd też współpraca sklepień z nadbudową była symulowana w programie obliczeniowym Atena na podstawie wcześniej wykonanych eksperymentów.
