Constructive Approaches to Reducing the Number of Antiseismic Seams for Buildings of Complex Shape

Abstract

The study of constructing buildings with complex plan configurations in seismically hazardous areas, while expanding design variability, represents a relevant direction in the field of earthquake-resistant construction. This is associated with a wide range of volumetric and spatial solutions proposed by architects, which often prove impracticable when seismic joints are required. The article discusses the possibility of designing buildings with complex plan configurations in seismic regions without the installation of seismic joints. In certain cases, the elimination of seismic joints can be achieved through the introduction of rigid cores in the most critical zones. This approach is proposed for the construction of buildings with complex plan configurations without subdividing them into separate simple-shaped blocks in order to meet seismic resistance requirements. In some situations, the introduced rigid cores may be regarded as seismic protection measures that make it possible to dispense with seismic joints.
