Description
  • Tento příspěvek se zabývá vlivem slunečního záření na deformace a stav napjatosti katedrály sv. Víta, která spadá do světového dědictví UNESCO. Snaha zachytit včas případný degradační proces vedla k monitorování nosné konstrukce katedrály sv. Víta. Během monitoringu byly zjištěny posunutí mezi monitorovacími body. Předpokládalo se, že naměřená posunutí jsou způsobena teplotní roztažností konstrukce. Tato skutečnost byla důvodem k provedení teoretického výpočtu deformací, které jsou způsobeny změnami teploty konstrukce. V tomto výpočtu byl zahrnut i vliv slunečního záření. Porovnáním teoretických a naměřených hodnot posunutí byla potvrzena hypotéza, že naměřené posunutí jsou způsobeny zejména délkovou teplotní roztažností konstrukce. Jedna část tohoto příspěvku se zabývá analýzou napjatosti opěrného systému katedrály sv. Víta. Opakované teplotní namáhání opěrného systému může vést ke vzniku únavových trhlin v konstrukci. (cs)
  • This paper deals with the influence of solar radiation on the deformations and state of stress of Saint Vitus' Cathedral, which falls within the UNESCO World Heritage reserve. Tendency to detect possible degradation process early enough leads to do monitoring of the Cathedral load bearing structure. The displacements between monitoring points were detected during monitoring. It was expected that measured displacements are caused by the thermal expansion of the structure. This was the reason to make the theoretical analysis of computation displacements with the influence of solar radiation. By the comparing theoretical and measured values of displacements it was detected that measured values of displacements are caused mainly by thermal expansion of the structure. One part of this paper is about the stress analysis of the Saint Vitus Cathedral bearing system caused by the temperature changes, which can cause the origin of the cracks in this bearing system.
