Calculation of reinforced concrete beam line includes a selection of the reinforcement beam with minimum effort on your part. You will need to set up the basic data:

1. Select your scheme supporting beams (in most cases "hinge-joint"

2. Set the length of the beam (set a calculated length of the beam is desirable, it is usually less than the actual length of the value of supporting beams, but the actual length less will do!)

3. Set the load on RC beam

4. Set the size of the beam section bxh mm.

5. Select your reinforcement beams (two options: only the bottom fittings and valves above and below).

Note: the calculation of the beam with the scheme "free end" the program already takes into account the fact that the tension reinforcement is from above, and compressed from below!

6. Select the class of concrete and rebar.

Concrete:
- C8 / 10 or B10
- C12 / 15 or B15
- C16 / 20 or B20
- C20 / 25 or B25
- C25 / 30 or B30
- C30 / 37 or B35
- C35 / 45 or B45
- C40 / 50 or B50
- C45 / 55 or B55
- C50 / 60 or B60
- C55 / 67
- C60 / 75
- C70 / 85
- C80 / 95
- C90 / 105

Frame:
- Smooth S240, A240, (instead of A-I)
- periodic profile S400, A400 (instead of A-III)
- periodic profile S500, A500 (new class)
- periodic profile A600 (instead of A-IV)
- periodic profile A800 (instead of A-V)
- periodic profile A1000 (instead of A-VI)
- Periodic Profile B500 (return Bp-I)
- Periodic Profile Vr1200 (instead of Bp-II)
- Periodic Profile Vr1300 (instead of Bp-II)
- Periodic Profile Vr1400 (instead of Bp-II)
- Periodic Profile Vr1500 (instead of Bp-II)

7. Ask the protective layer of concrete (you can set a variety of ways: on the operating conditions of the class working conditions, as well as easy to enter.

As a result, the calculator will give you a concrete beam diameter and number of selected reinforcement.

The calculation is performed according to the "NSS 5.03.01-02 Concrete and concrete structures".

The calculation results to take reference.
