How to define and modify concrete base material in Concrete-over-metal-deck module

Summary

Defining the base material correctly ensures that PROFIS Engineering applies the appropriate concrete properties such as strength, cracking condition, and lightweight classification, when evaluating anchor performance in concrete‑over‑metal deck applications. These settings directly influence capacity calculations, safety factors, and installation requirements.

Prerequisites

Make sure you:

Are logged in to your PROFIS Engineering account
Have opened the Concrete-over-metal-deck module

If needed, refer to the article How to access the Concrete-over-metal-deck module in PROFIS Engineering .

Step-by-step instructions

Open the Base material tab
In your Concrete-over-metal-deck design workspace, navigate to the Base material tab on the left-hand side of the screen.

Define Concrete base material
Open the Base material section
Expand the Base material section to view the available inputs.
Specify the concrete cracking condition
By default, cracked concrete is enabled as most structural slabs experience cracking under service loads.
Disable this option only when you have confirmation that the concrete will remain uncracked during service conditions.
Select the concrete strength class
Use the dropdown menu to select the concrete strength.

Alternatively, select Custom to enter a specific value.
Enable Lightweight Concrete (if applicable)
If the slab uses lightweight concrete, enable the Lightweight concrete option.
