Introduction

The course design provides for the design of structural reinforced concrete elements of the building: multi-pillar slab, girder, column and foundation. The design is carried out according to the regulatory documentation: SP 63.13330.2018 Concrete and reinforced concrete structures. Main provisions, GOST 25902006 Rolled-stock steel hot-rolled round. Sortament.

Purpose of the course design: calculation of reinforced concrete bearing structures and selection of reinforcement according to calculations .

In longitudinal and transverse directions, the rigidity of the building is provided by rigidity diaphragms (connecting system).

The building contains 11 floors, as well as a basement. Construction area - Tyumen.

Column Calculation and Design

For the designed 11-story building, a precast reinforced concrete column with a section of 40 × 40 cm is adopted. For columns, heavy concrete of compression strength classes not lower than B15 is used, and for heavily loaded ones, not lower than B25. The columns are reinforced with longitudinal rods with a diameter of 16... 40 mm from hot rolled steel A400, A500 and transverse rods mainly from hot rolled steel of class A240.

Conclusion

During the course project, load-bearing reinforced concrete elements of the 11-storey building were designed: a multi-storey slab, a girder, a column and a foundation. The design was carried out according to the regulatory documentation: SP 63.13330.2018 Concrete and reinforced concrete structures. Main provisions, GOST 25902006 Rolled steel high-rolled steel round. Sortament.

Calculations of reinforced concrete bearing structures and selection of reinforcement according to calculations were made.
