Dilatation of the High-Rise Building by Inserted Field

Abstract

The dilatation of the high-rise building by inserted field is the main topic of this paper. This building contains of two “towers” with different heights (8-storey and 25-storey), which are linked by inserted field. The description of the building and applied loads are shortly mentioned. The paper is mainly focused on the importance of the dilatation and its types, the modelling of inserted field and its structural solutions. The comparisons of horizontal forces due to the wind load and seismic load are presented at the end. The solution was recalculated for four seismic areas in Slovakia, where different values of basic seismic acceleration ar are. Also, the maximum horizontal deflections calculated for three alternatives of the building (without dilatation, with continuous dilatation 50 mm located between two “towers” passing through the foundation, with dilatation by inserted field between two “towers”) due to static wind load are presented here.
