Please follow the instructions provided below to set material definitions to be used in this bridge example.
Navigate to Properties > Materials |  |
Click the three-dots on the first cell of the Name and click Import Material | |
Import following materials from OpenBrIM Library
|    |

Each material type comes with a default curve, which you can view from this menu. If you need to customize it, you can introduce a new library component. To assign a different curve, simply select it from the selection box. These curves will be used to compute the section capacity based on the strain compatibility method. To view a sample of these default curves, follow these steps: Click on the three dots in the first cell of "A615_60" and select Edit

Define a custom Concrete material manually as Fc_3_1/2ksi_NoStiffness. The purpose of defining such a material is to introduce components without their stiffness. In this example, we will assign this material to a barrier and eliminate its stiffness during construction. |  |
Copy and paste the data below for the Fc_3_2ksi_NoStiffness. Fc_3_2ksi_NoStiffness 0.0004 0.0000 0.0002 149.9904 6.0000 concrete Mander Concrete | |
To introduce a new material, add a new row and specify RigidMaterial as its name. As a general practice, make sure to set the unit weight of rigid materials to “0”. | |
Copy and paste the data below for the RigidMaterial. RigidMat 4307.0000 0.2000 1794.5830 0.0000 6.5000 steel Bilinear Steel |
Completed material definitions are illustrated below.
