1. General Directions and Task

The purpose of the course design is to master the basics of calculation and design of reinforced concrete structures, to study the method of calculation of reinforced concrete structures by limit states (bearing capacity, deformations, crack formation and opening).

The course design is carried out on the basis of the design task and consists of a calculation explanatory note with a volume of 50 sheets and a graphic part with a volume of seven drawing sheets of A3 format. The completed drawings shall comply with the requirements of the standard [4]. The composition of the explanatory note is detailed in the sections of these methodological guidelines.

Task

Perform a working design of structural structures of a multi-storey civil building (see Figures 1.1 and 1.2) with a full frame, including calculation and design of the following structures:

- prefabricated floor panel with stressed reinforcement;

- single-span girder;

- First floor precast column.

The student takes the initial data strictly on the last two digits of the cipher (tables 1.1 - 1.3).

Table 1 shows the pitch of the columns l1 x l2, with l1 being the pitch in the transverse direction and l2 being the pitch in the longitudinal direction.

The building has four spans in the transverse direction and six spans in the longitudinal direction.

The main load-bearing structures of the multi-storey frame building are reinforced concrete frames, vertical connecting diaphragms and their connecting interstage floors. Girders are used single-span T-section with hinged support on column consoles. Floor slabs are multi-empty with three types of circular voids (Figure 1.1): P1 - row; P2 - good; P3 - bundled, laid in rows of columns.
