RTI Expert 011267
RTI Expert 011267 is internationally recognized for his research on the effects of chemicals and chemical processing on the structural performance of wood and wood composites. This research has resulted in over two dozen peer-reviewed publications on the effects of preservatives and preservative treatment on the physical and mechanical properties of wood. His research has resulted in several new design adjustments or process limitations in
National Codes and Standards in the US and Canada.
Our expert is widely recognized for his research and technological development of the concepts of using engineered biocomposites as a value-added tool to promote and to fund sustainable forest management. He formerly led this emerging approach through his long-work with the International Union of Forest Research Organizations (IUFRO) Division 5 Forest Products.
His work on the very early stages of biological decay showed that changes in the chemical composition of the wood cause significant reductions in wood strength before measurable weight loss occurs. From an engineering perspective, estimating strength loss and residual strength is the critical element in assessing wood serviceability/durability for structures in-service as affected by wood decay. Collaborative studies have shown close a relationship between the degradation of hemicellulose and wood strength losses. Residual strength of degraded wood can be predicted using models developed by this collaborative team. The changes in chemical composition appear to be similar in both the biological and chemical systems. Understanding the relationship between chemical composition and strength loss is critical in developing models to estimate strength loss caused by biological, chemical or thermal agents.
