Introduction

Reinforced concrete consists of concrete and steel reinforcement, working together, due to the adhesion that occurs between them. Concrete is an artificial stone material, resists compression well, and works 15... 20 times weaker for stretching. To increase the strength of concrete, reinforcement is used, which has a significantly higher tensile strength and allows to significantly increase the bearing capacity of building structures.

The main advantages of concrete are high strength, durability, fire resistance, weather resistance, the possibility of using local building materials, ease of forming, low operating costs.

Architectural and structural solution of the building

In accordance with the assignment, a rectangular building with dimensions along the extreme axes of 17.98x10.2m. Floor height 2.8 m.

The building is designed with transverse bearing walls. Spatial rigidity and stability of the building is provided by dressing of vertical seams between bricks, reinforcement of angles and places of adjoining internal walls to external and anchoring slabs with a wall (L-shaped anchor) and to each other (linear anchor).

In terms of durability, the building belongs to the II degree, since its structural elements are designed for a service life of at least 50 years.

In terms of fire resistance in accordance with SNB 2.02.0198, the building belongs to the III degree.

Building liability class as per SNiP 2.01.0785 - III.

The building is located on a site with a calm relief. At the base lies soil - gravelly sand.

Conclusion

During the course work on the structures, knowledge was gained. He learned to calculate a bar jumper, floor slabs, and a ribbon foundation. He mastered the principle of calculations of reinforced concrete products.

There were significant difficulties in performing graphic work, but they were successfully eliminated. Methods of reinforcement, reinforcement elements have been properly studied.

The course was complex and voluminous. Sometimes a little interesting.
