FIELD: construction industry, specifically, columns, flooring, wall partitions and beams. SUBSTANCE: objective of invention lies in manufacture of profiled article from wood that allows resistance to shearing force and impact loads in composite wooden structures as well as rated load capacity without additional reinforcement to be raised. This objective is reached in the following way: profiled elongated wooden article has first longitudinal facet with rectangular protrusions, surfaces of protrusions being parallel to longitudinal direction of elongated article, and flat facet. Surfaces of specified protrusions are parallel and perpendicular to second flat facet. Second facet is longitudinal facet carrying rectangular protrusions, first and second groups of surfaces of protrusions are correspondingly parallel and perpendicular to second flat facet. Composite wooden structure includes assemblage of articles. Process of manufacture of composite wooden structure consist in butt joint of protrusions of one article with another article with use of glue. EFFECT: raised resistance to shearing force and impact loads. 21 cl, 14 dwg
