The paper presents a study of stiffness of wood Cambará (Qualea sp.) exposed to high temperatures, trying to verify aspects of fire safety in roof structures evaluating an alternative method of study of the mechanical properties of wood subjected to high temperatures. The study was conducted at the Campus Experimental de Itapeva - UNESP. For exposure to high temperatures muffle was used with the samples being subjected one at a time from 200°C rising to 100°C to 100°C, up to the 1000°C or even especimen withstand the test of compression parallel to grain. The maximum temperature reached was 700°C, and after that mark the specimens were sectioned to continue their studies. The method resembled a real fire and was efficient since, according to the Eurocode 5 (2002), the rate of carbonization of wood Cambará study was similar to that prescribes that the normative document
