Structural Concept Features of Suspended Structures for Seismic Areas

Abstract

The key task of the building design is the comprehensive elimination of hazards arising from various impacts on buildings, including seismic ones. Recently, new structural systems have been developed to ensure the earthquake resistance of buildings, as well as the already known ones are being improved. One of the types of structural systems that can be used in seismically active areas are buildings with suspended structures. There are many design solutions for buildings with suspended structures that differ in the type of supporting structure, suspension system and geometric shape. The possibility of using suspended structures under dynamic influences is explained by a load decrease in the load-bearing elements of the building due to the flexibility of these structures, as well as a large natural period of oscillations of buildings with suspended structures. Some aspects of the use of buildings with suspended structures are not fully understood, which prompted a study of the behavior of these buildings using various structural solutions in earthquake conditions. For the effective use of these structures in the practice of earthquake-resistant construction, an important issue is to understand the behavior of suspended structures under seismic influences of a wide frequency spectrum. The results of the study are presented in the paper.
