The calculations in this Section are presented in the following parts:

4.2 A simply supported continuous beam showing what might be deemed typical hand calculations.

4.3 A heavily loaded L-beam.

4.4 A wide T-beam. This example is analysed and designed strictly in accordance with the provisions of BS EN 1992-1-1.

They are intended to be illustrative of the Code and not necessarily best practice.

A general the method of designing slabs is shown below:

1. Determine design life.

2. Assess actions on the beam.

3. Assess durability requirements and determine concrete strength.

4. Check cover requirements for appropriate fire resistance period.

5. Calculate minimum cover for durability, fire and bond requirements.

6. Determine which combinations of actions apply.

7. Determine loading arrangements.

8. Analyse structure to obtain critical moments and shear forces.

9. Design flexural reinforcement.

10. Check deflection.

11. Check shear capacity.

12. Other design checks:

Check minimum reinforcement. Check cracking (size or spacing of bars). Check effects of partial fixity. Check secondary reinforcement.

13. Check curtailment.

14. Check anchorage.

15. Check laps.
