Beams Design according to Eurocode

General
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. <BS EN 1990 & NA Table NA.2.1>
2. Assess actions on the beam. <BS EN 1991 & NAs>
3. Assess durability requirements and determine concrete strength. <Table 4.1> <BS 8500-1: Tables A4, A5>
4. Check cover requirements for appropriate fire resistance period. <BS EN 1992–1–2: Tables 5.8, 5.9, 5.10, 5.11>
5. Calculate minimum cover for durability, fire and bond requirements. <4.4.1>
6. Determine which combinations of actions apply. <BS EN 1990 & NA Tables NA.A1.1 and NA.A1.2 (B)>
7. Determine loading arrangements. <5.1.3(1) & NA>
8. Analyse structure to obtain critical moments and shear forces. <5.4, 5.5, 5.6>
9. Design flexural reinforcement. <6.1>
10. Check deflection. <7.4>
11. Check shear capacity. <6.2>
12. Other design checks:
- Check minimum reinforcement. <7.3, Tables 7.2N, 7.3N>
- Check cracking (size or spacing of bars). <9.3.1.2(2)>
- Check effects of partial fixity. <9.3.1.1(2), 9.3.1.4(1)>
- Check secondary reinforcement. <9.3.1.1(1), 9.2.1.1(1)>
13. Check curtailment. <9.3.1.1(4), 9.2.1.3, Fig. 9.2>

14. Check anchorage. <9.3.1.2, 8.4.4, 9.3.1.1(4),
9.2.1.5(1), 9.2.1.5(2)>
15. Check laps. <8.7.3>
