To assess a structure (whether it is sufficiant or not), the following steps must be followed in sequence:

- Schematising the construction
- Determining the internal forces and moments (= global analysis, elastic analysis)
**Checking the cross-sections (= design):****Strength****Stability****Stiffness**

The explanation below covers the design of concrete.

## In Diamonds

- Generate at least the combinations in ULS FC, SLS RC and SLS QP.
- Determine which analysis type you’re going to use. Based on the analysis type you’ve chosen:
- (un)check the buckling verification
- enter the correct value for the accidental eccentricity δ
_{a} - set the buckling lengths (if required)

- Calculate the internal forces
`F9`or. - Select the correct concrete standard with
**Analysis > Concrete standard**. - Click on
`F2`or to calculate the reinforcement. The calculated reinforcement will take the strength and stability requirements into account. Related articles: - Click on to calculate the deformation/ cracking widths (= verifying the stiffness).
- Check the option ‘Compute deformations after creep’.
- If the model contains walls or plates loaded with axial force, also check the option ‘Extend cracking theory to axial forces’.

- Verify the cracked deformation.
- Verify the cracking widths w
