Abstract: As a requirement for the use of wood in civil construction, it is necessary to first understand its properties and what can modify its performance, such as its moisture content, which is inversely proportional to its mechanical strength and can become an aggravating factor for the development of pathological manifestations. This study aims to analyze whether the direct use of wood marketed in the municipality of Gurupi - TO, without prior drying, in building structures may be affected by excessive moisture. Additionally, the study seeks to examine the parallel compression strength of the wood fibers and correlate it with other strengths based on a simplified analysis of the ABNT NBR-7190 standard (1997). The species Manilkara spp. was used for the study, as it has good performance in structures and is locally available for purchase. Finally, it was observed that the wood is being sold within moisture classes 1 and 2, and the results of compression, tension, and embedment are equivalent to those specified in the Brazilian standard and other sources. Regarding the compression strength values, a correlation was obtained between the averages with a significance level of 5%, which was not the case for the moisture content test. Efforts were also made to understand the reasons for the reduced use of wood in structures and to encourage further research on cataloging regional wood species for structural use and the study of causes of pathological manifestations as a variation of the study.
