Materials

The Materials tab allows you to view, edit, and customise the material models used in your sections.

All materials shown are generated automatically based on the design code selected in the Setup section. The available material models and parameters depend on the selected design code.

Available material types​

Depending on the selected design code, the following material types may be available:

  • Concrete
  • Reinforcement
  • Steel
  • FRP

Viewing stress–strain curves​

Selecting a material displays its stress–strain behaviour in the chart.

The chart shows:

  • ULS (Ultimate Limit State) curve
  • SLS (Serviceability Limit State) curve
  • SLS (Serviceability Limit State) long-term curve

Multiple materials can be selected at the same time to compare their stress–strain behaviour on a single chart.

Long-term effects and creep​

You can visualise the effect of creep on material behaviour by:

  • Enabling the SLS long-term curve using the chart legend
  • Adjusting the creep coefficient

This allows you to see how long-term effects influence the stress–strain response of the material.

Editing materials​

To modify a selected material, first select the duplicate icon, then select the user-defined copy, and finally select the pencil icon.

You can edit:

  • General material parameters
  • ULS parameters
  • SLS parameters

Any changes made here directly affect the corresponding stress–strain curves shown in the chart and used for analysis.

Changing the material model​

Within both the ULS and SLS tabs, you can change the material model by selecting an alternative option from the dropdown list.

This allows you to explore different material formulations while remaining compliant with the selected design code.

Defining custom stress–strain curves​

It is also possible to define a custom stress–strain curve by selecting the Explicit option.

You can define the curve by:

  • Importing a CSV or text file, or
  • Manually entering coordinates by pasting data using the input icon

Once defined, the material is marked as modified and the stress–strain curve no longer follows the standard code‑based shape (for example, a rectangular parabola).
