Timber Roof Panel for Industrial Buildings: Analysis According to Bending Stiffness Condition

Large-span roof structures allow creating spacious rooms without using intermediate supports, which is important for a flexible planning system of industrial and public buildings. Typically, such structures are made of metal or reinforced concrete trusses or arches. The object of the study is a new ridged structure of a wooden plank roof panel for industrial buildings with spans of 24 and 30 m. The width of the panel without rafter structures is 2.4 m. The connection of individual boards and elements with each other in the panel is provided by nails and bolts, which compares favorably with glued wooden structures. It is possible to assemble the structure directly on the construction site. There is no need to deliver a large-scale product to the installation site. The article provides a detailed analysis of design solutions, presents calculation methods, as a result of which it is determined that the proposed structure meets the condition of bending rigidity. A simple to manufacture and to install system is described, based on the use of wooden boards and panels, which provide the nec-essary overall stability of the structure, making it an attractive option for use in various climatic regions. The results of the studies confirm the high potential for further implementation of such technology in real design practice.
