Análise das propriedades da madeira de estrutura de telhado após a ocorrência de um incêndio

The present study evaluated the mechanical properties of pieces of wood coming from the roof structure of a residence subject fire in the rural area of Itapeva/SP. The structure was built 25 years ago using wooden beams of the species Guarucaia (Peltophorum vogelianum), where the specimens were removed. The research methodology included qualitative evaluation of the samples, estimating the layer pyrolysis and carbonization of the wood, measuring of density and mechanical tests of compression parallel to grain, tension parallel to grain and shear. The mechanical properties of wood were analytically correlated with the layers carbonization and pyrolysis that are influenced by the temperature and time of fire; these values were estimated at 1000 °C and two hours for the case in question. The results indicate that the strength properties of degraded wood are different from a healthy wood. The level of thermodegradation, in general, can be measured by density, result in weight loss due to decomposition of the wooden components.

Distribuição espacial dos incêndios em vegetação registrados pelo 2º Sub-Grupamento do Corpo de Bombeiros de Rio Claro/SP e o tempo atmosférico entre 2009 e 2013

Many fire occurrences in vegetation happen annually in the city of Rio Claro, causing material losses, environmental damage and discomfort to population. When identified the source, notes that the higher index is intentional, however, climatic factors such as wind speed, temperature, relative air humidity, rainfall, or even the local relief also affects in the spread and its devastating effects. Scientific studies that would assist the local community in the prevention and repression of them still are scarce. This way, the work has as objective contributes in the understanding of the relationship among the fire occurrences in vegetation registered (recorded) by Fire Department of Rio Claro/SP, and their relationships with the atmospheric time. To achieve this goal was made to build a database related to fires in vegetation during the years 2009-2013, and subsequently correlated with data of precipitation and relative humidity the air, provided by Center for Analysis and Planning Environmental (CEAPLA). The result identified the profile of the fires, the seasons of higher frequency, neighborhoods and districts with the highest number of records and correlate events with climatic factors that act in the ignition, propagation and control of fires in the Municipal district of Rio Claro/SP
