Abstract
As the height of the building increases, loads on load-carrying structures increase dramatically, and as a result of the development of high-rise construction, several structural systems of such buildings have been developed: frame, frame-frame, cross-wall, barrel, box-type, box-to-wall ("pipe in pipe", "Trumpet in the farm"), etc. In turn, the barrel systems have their own versions: cantilever support of the ceilings on the trunk, suspension of the outer part of the overlap to the upper carrying console "hanging house" or its support by means of the walls on the lower bearing cantilever, intermediate position of the supporting cantilevers in height to the floor, from a part of floors. The object of the study are the structural solutions of high-rise buildings. The subject of the study is the layout of structural schemes of high-rise buildings, taking into account the main parameters - altitude (height), natural climatic conditions of construction, materials of structural elements and their physical and mechanical characteristics. The purpose of the study is to identify the features and systematization of structural systems of high-rise buildings and the corresponding structural elements. The results of the research make it possible, at the stage of making design decisions, to establish rational parameters for the correspondence between the structural systems of high-rise buildings and their individual elements.
Highlights
High-rise buildings have a specificity, significantly different from them traditional highrise buildings and multi-storey buildings
Complex solutions of internal engineering systems and communications, accompanied by the creation of additional engineering units, which is due to the height of the building;
Increased requirements for integrated security, including firefighting, involving the use of technical solutions of a qualitatively different level and affecting the choice as volumeplanning, and constructive decisions. These aspects must be taken into account when choosing a structural scheme of a highrise building and designing load-bearing structures
Summary
High-rise buildings have a specificity, significantly different from them traditional highrise buildings and multi-storey buildings. Increased requirements for integrated security, including firefighting, involving the use of technical solutions of a qualitatively different level and affecting the choice as volumeplanning, and constructive decisions These aspects must be taken into account when choosing a structural scheme of a highrise building and designing load-bearing structures. Despite the fact that this experience is permanently generalized by researchers in this field of construction, the appearance on the world map of each new high-rise building is of interest to a large number of specialists dealing with the problems of developing new building materials, non-traditional structural solutions for load-bearing and enclosing structures (including facades) , dealing with issues of hydrogeology, improvement of engineering systems, architects and city planners, construction monitoring services, etc. The unique experience in the world practice of design and construction of high-rise buildings is enriched by new objects every year, taking into account the various conditions for the construction and operation of these buildings and the trends in the development of the society's needs at the present stage in ensuring the quality of living and a comfortable environment of life activity [20-22]
