Control Tests of Long-Span Laminated Timber Structures with Nodes on the Glued-In Rods

Large-span laminated wooden structures have large dimensions and require the creation of knots and joints to divide the structures into technological elements, convenient for manufacturing and installation. This problem is solved by using both traditional and new types of knot joints. New types of knots include connections on glued rods. If in Europe there was the way to create knots with rods glued along the fiber of the wood, or along and across the fiber, in Russia the focus was on the knots of laminated wooden structures with reinforcing rods glued at an angle to the fiber of the wood. Under the leadership of S.B. Turkovsky the systems of knotted connections on glued rods - “CNIISK systems” were developed. Hundreds of objects were built using this system. Such objects often require control tests. In most cases, the tests are not performed on structures, but on fragments with assemblies in full size. The rationale and purpose of control tests are given. Examples of control tests during the construction of long-span buildings and structures with glued wood frameworks, carried out by the laboratory of wooden structures of the Kucherenko Central Research Institute of Scientific and Technical Cybernetics under the guidance of V.A. Kucherenko Institute of Wooden Architecture and Construction are given.
