Abstract
Assessment of the bearing capacity of U-shaped arch profiles for the construction of frameless arch coverings under the climatic conditions of the Republic of Khakassia
Incoming article date: 18.02.2022Frameless arched coverings are one of the varieties of prefabricated structures for various needs: sports facilities, hangars for various equipment, warehouses for vegetable storage, etc. They are economical compared to other structures, since due to their light weight they do not require massive foundations, compared to frame and wall structures and can be laid with a small depth, which in turn saves on land work. Due to this, they arouse interest in their design and in the development of structural improvements, especially for conditions with a sharply continental climate with high precipitation and strong winds. In this paper, frameless arched coverings made of U-shaped profiles were considered, depending on the span of the coating and on the method of insulation for the sharply continental climate of the Republic of Khakassia. As a result, we have received that constructive solutions are required to strengthen these coatings for large spans, for example 15, 20 and 25 meters, or measures to reduce the snow load on the coating.
