Introduction

Reinforced concrete in the construction of Russia occupies a leading place. The scale of the use of reinforced concrete is due to its high physical and mechanical indicators, durability, good resistance to temperature and humidity effects.

When completing the course "LBC and stone structures," it is necessary to consolidate the acquired knowledge and gain practical experience in calculating reinforced concrete structures.

The objectives of the course project are:

- fixing of passed theoretical material;

- mastering practical methods of independent calculation and design of the most common types of structures: monolithic hollow slab, girders, prefabricated reinforced concrete column and foundation for the column.

General Design Data

The five-story frame building has a size in plan 14, 4m × 32, 4m and a grid of columns 4, 8m × 5, 4m. Floor height 3.6m. Reinforced concrete structures made of heavy concrete.

Standard load on floors is 2.5kPa (kN/m2). Load safety factor is taken as per SNiP 2.01.0785 * "Loads and impacts." The responsibility factor of the building in accordance with GOST 277512014 "Reliability of building structures" is taken equal to 1.0.
