ANALYSIS OF DEFORMATIONS OF CYLINDRICAL VAULTED ROOFING OF RELIGIOUS BUILDINGS

Abstract

Statement of the problem. Most of the modern architectural monuments, in particular religious buildings, are made of stone or baked bricks. The end of the 19th century brought new progressive materials to the construction industry. Their widespread use for a long time pushed into the background not only stone construction but also all kinds of studies of vaulted and arched brick elements. A lot of influencing factors led to the damage, in particular the formation of cracks, the effect of which on the supporting structures has not been sufficiently studied so far. Results. To study the effect of these damages on the load-bearing capacity, we carried out and analyzed numerical and physical experiments. We took as an analogue for the study «The Temple in Honor of the Nativity of the Blessed Virgin Mary (Rozhdestva Presvyatoy Bogoroditsy)» in the village of Kabalichi, Bryansk region, Russia. We carried out an instrumental inspection of the monument, built and tested a laboratory model of the original structure.Conclusions. A sufficiently serious damage that can lead to cracking in the bearing structures of the vaults is the displacement of the supports. However, cracking occurs at rather large displacements and does not always lead to the exhaustion of the load-bearing capacity of the roof.
