Engineered composite lumber is one of sawn wood alternative. The product described herein utilizes a modified form of sawn lumber as the raw material. The objective of this research was to manufacture, and evaluate a novel type of engineered lumber by non destructive evaluation and mechanical testing and compare the design values to those published by the U.S. (NDS) for wood construction. Pine logs were into matched symmetrical trapezoids. Symmetrical trapezoids were evaluated non-destructively and sorted by results to be matched into pairs and assembled into Bowtie Beams....
