How to define longitudinal reinforcement in existing concrete member in Post-installed rebar module

Summary

Defining the longitudinal reinforcement in the existing concrete member allows PROFIS Engineering to accurately model the reinforcement that the post-installed rebar will splice into. Providing precise reinforcement details ensures correct calculation of development length, anchorage behaviour, and load transfer in the Post‑installed Rebar module.

Prerequisites

Make sure you:

Are logged in to your PROFIS Engineering account
Have opened the Post-installed rebar module

If needed, refer to the article How to access the Post-installed rebar module in PROFIS Engineering .

Step-by-step instructions

Open the Existing reinforcement tab
In your Post-installed rebar design workspace, navigate to the Existing reinforcement tab on the left-hand side of the screen.
Select the format for entering reinforcement details
Under Longitudinal reinforcement, choose whether you want to define reinforcement using Reinforcement layers or Reinforcement arrangement.
Enable Changes in cast-in rebars affect post install rebar positions if applicable.
Enter reinforcement details
If Reinforcement layers is selected, enter the following parameters: Shape, Bond condition, Front cover and no. of layers.
For each layer specify: Diameter, Bar arrangement and Top cover.

If Reinforcement arrangement is selected, enter the following parameters: Shape, Bond condition, Diameter, No. of bars in x and y direction, Side cover and Front cover.
