Abstract

[The possibility of using high-performance concrete on the example of a business center project with a height of 104.0 m, the concrete of which is class B40, was considered. We carried out the collection of loads (the loads from snow and wind were taken into account) and performed the calculation of structures for strength in the software application LIRA-CAD. We considered the vertical load-bearing elements as columns of square section and horizontal carrying elements as the base plate and floor slabs. As a result, we obtained the stress mosaics for horizontal elements and the required reinforcement areas for vertical. Changes in the stress–strain state are turned out to be significant for columns and less noticeable for slabs since in high-class concretes, the compressive strength increases more than the bending strength. Different reinforcement options for square columns are selected. We made an estimated calculation of the cost per linear meter of the reinforced concrete column construction for three cases of combining material and geometric characteristics: the class of concrete B40 for columns with a cross-section of 600 × 600 mm, originally adopted in the design of the business center, and the increased class of concrete B80 for columns with a cross-section of 600 × 600 mm and 500 × 500 mm. The use of class B80 high-performance concrete reduced the cost of the structure by 8% while maintaining the cross-section, due to less reinforcement. It was also possible to reduce the cross-section of the column from 600 × 600 mm to 500 × 500 mm without increasing the initial cost.]
