Proposta para análise da resistência de telhas de barro, fibrocimento, cerâmica e de concreto quando submetidas a chuvas de granizo

Abstract

The roofs have the main function of protecting buildings from atmospheric effects (rain, sun, wind, snow, etc.). In addition to physical protection roofs contribute to the thermal and acoustic comfort of buildings. Normally, in Brazil, there are no extreme weather events (tornadoes, snow, hurricanes, etc.), but in the last decade started to be some weather events that, until then, had never happened - or happened very rarely and with little intensity (mainly hailstorms, and more rarely made low-grade). Previously hailstorms in Brazil had low destructiveness and high occurrence of time, but in the last five to ten years began to experience these events more often. Mainly in the southern region of Brazil. It is worth noting that rarely verified studies or procedures on the recommendation tiles exchanges to homes reforms (either occurrence of reasons of extreme weather events in certain regions or their life ended). Thus, this research sought develop a method and test execution procedure to evaluate the behavior of some usual patterns of tiles comparing the strength conditions.
