THE STUDY OF COMPLEX STRESS STATES OF ELEMENTS FILLING THE CELLS BETWEEN THE RIBS OF WOODEN LARGE-SPAN DOMES
Journal Title: International Journal for Computational Civil and Structural Engineering - Year 2019, Vol 15, Issue 1
Abstract
The article is devoted to the research of complex stress states of anisotropic materials under long-term loads. The article considers the design of criteria for short-term and long-term strengths proposed by G.A. Geniev in connection with the calculation of large-span structures of domes of laminated and solid wood, where the enclosure elements are included in the joint work with the power set in the form of meridional and circular ribs. In this case, the elements of an enclosure-plate are at a complex stress state and they work under compression with a shift. Joint work of such systems was studied by experiments on large-scale models and experimental construction. Large reserves of strength resistance are revealed. In particular, in 1985, the indoor skating rink at the stadium “Lokomotiv” was built as an experimental facility which implemented these conditions and it has been successfully operated for many years. However, there are some unsolved issues with the refinement of the actual operation of the structures and the development of the calculation algorithm. Some generalizations of the studied approaches are given.
