Abstract
Introduction: One of the main problems in wooden structures is that over time and under various climatic conditions, they are attacked by insects and fungi, causing relevant structural damage. Damage caused by chestnut rot fungi can lead to significant structural failure in a short time. Objective: To evaluate the variation of physical-mechanical properties in wood elements of Pinus radiata D. Don with the presence of chestnut rot. Methodology: Three samples with the presence of chestnut rot and three control samples (without visible deterioration) are taken, specimens are made from them and tests are carried out for compression parallel to the fiber, normal compression and static bending according to the standard. ASTM D143. Results: The samples with the presence of rot showed notable reductions in apparent elasticity modulus and rupture modulus for the three tests carried out. Also, density losses of up to 39% could be observed in contrast to the average of the control samples. Conclusion: The visible deterioration in elements with the presence of chestnut rot can be related to important losses in the mechanical properties mentioned in this document. Additionally, it should be considered a warning sign for the health of the structure. General study area: Civil engineering. Specific study area: Structures.
