Systems with rigidity cores and high-rise buildings outriggers

The article deals with the problems of applying systems with stiffeners and outriggers for high-rise buildings. The analysis of various designs is carried out, the features of their work are specified, the advantages and disadvantages are identified, the areas of their application. When designing and building high-rise buildings, it is necessary to ensure their resistance to lateral loads arising from wind or seismic influences. The article shows the ways of solving this problem based on various constructive systems. Particular attention is paid to the use of outrigger link systems for providing high-rise buildings rigidity. Various variants of outriggers are investigated in the paper, their advantageous sides and disadvantages are compared, the types of their optimal solutions are determined. A number of technical and economic problems of high-rise buildings with stem systems and outriggers, which have not been sufficiently investigated, are mentioned. Recommendations are given on the use of systems with stiffeners and outriggers to increase the rigidity and lateral stability of high-rise buildings
