| Title of the article | Modelling the stages of construction, operation and structural safety of long-span unique buildings |
| Abstract. | Problem statement. The main problem of the study is to ensure the structural safety of long-span unique buildings and structures using spatial shell structures made on full-scale structures subjected to long-term static and short-term dynamic impacts of a high level. The purpose of the work is to simulate the behavior of various geometric shapes of reinforced concrete spatial shell structures under static and dynamic effects of high intensity in order to identify characteristic features and ensure structural safety at the construction and operation stages. The objectives of the research are: ensuring operational safety using the modeling method, investigating changes in the structural properties of materials and dynamic parameters, assessment of the impact of climatic conditions, flexibility of structures, taking into account the presence of damage; study of external influences, introduction of stiffening elements to ensure seismic resistance and operational safety. Results. The paper proposes a method for ensuring the structural safety of long-span unique buildings under prolonged operational and seismic impacts of varying intensity, the introduction of spatial stiffness elements, the inclusion of which contributes to the exit from the resonant state of the spatial system. Conclusions. The significance of the results obtained for the construction industry lies in the possibility of ensuring the structural safety of long-span unique buildings at the stages of construction and operation, which makes it possible to expand the scope of effective types of spatial shell structures in regions with difficult natural and climatic conditions. |
