Modeling of Seismic Resistance of Spatial Larg-span Unique Structures in the Operational Stage

Abstract

Abstract The paper presents the results of the research of the stress-strain state of long-span unique spatial and shell constructions, subjected to long-term static and dynamic effects, and performed by using experimental methods of physical modeling obtained on experimental models and full-scale structures. To ensure the operational safety of buildings and structures, the change in the structural proper-ties of materials from unfavorable climatic conditions of long-term beyond design-basis static loadings dynamic effects of high intensity compliance of bearing diagrams and the presence of local damage to structures was investigated. The evolution of the dynamic parameters of spa-tial and shell constructions during operation is investigated.
