Features of designing high-rise buildings in seismic areas
In the design of high-rise buildings, consideration should be given to the possibility of seismic effects, even if the likelihood of their occurrence is very small. The design of buildings and structures in areas with high seismicity is carried out in accordance with certain requirements, taking into account the natural-climatic, hydrogeological, relief-landscape and other features of the area. The construction of multi-storey buildings in seismic conditions is an even more difficult task, since in addition to the general requirements for multi-storey construction, the requirement for their high reliability for seismic effects is added. This article discusses the design features of high-rise structures in seismically hazardous areas. The main methods of seismic protection are considered, in particular, various types of seismic isolators, as the most frequently used solution to achieve the required seismic resistance in both industrial and civil construction. High-rise, unique and highly complex buildings must be designed and constructed with a greater degree of reliability than conventional buildings in order to meet the assigned class of responsibility.
