Effect of single tube sections on the structural safety of Chinese solar greenhouse skeletons

Abstract In recent years, the use of single-tube skeletons for the construction of Chinese solar greenhouses has increased. As a consequence, during the selection of the construction materials, the safety of these structures has become an important issue. The single tube section has various forms, b...
