| Popis: | Nowadays, there are several existing masonry arch structures which are usually protected. Therefore, the maintenance and determination of their load-bearing capacity is a very important issue. Consequently, it is necessary to understand the behaviour of these structures, but the investigation of an old structure can cause difficulties. Nevertheless, a lot of tests can be performed on a smaller model under laboratory conditions. It is easier to understand their structural behaviour and determine the parameters that significantly influence the load-bearing capacity. It also gives the chance to build and verify a numerical model that can be used to model existing structures. In this research, destructive tests of small scale stone masonry arches were performed under laboratory conditions. The analyses were carried out with and without reinforcement to determine the differences in structural behaviour, load-bearing capacity, and failure type. For the tests, carbon fibre reinforced polymer (CFRP) plates were used to strengthen the arch. The properties of the building materials of the stone masonry arches were tested. The paper presents the results and experiences of the construction and the loading of small scale masonry arches. Furthermore, it gives a comparison between the behaviour of reinforced and unreinforced structures. |
