After each construction stage, the finite element analysis produces results that can be utilized to ensure structural compliance with codes. To create the stages correctly, users must understand the underlying logic. At the start of the stage construction analysis, all structural elements are in an unconstructed state.
Please follow the instructions provided below to construction stages.
| 1 | Navigate to Loading > Construction Stage |     |
| 2 | Begin by defining a construction stage and then enter the preceding stage for that construction stage. | |
| 3 | Ensure that the "Prior Stage" cell is “Null” as the first stage of the construction process does not have a preceding stage. | |
| 4 | To assign the data in the "Construction Method" and "Filter by load type cells" click on the three dot-icon and select the appropriate option from the combobox. | |
| 5 | Enter the data as follows for 1st Stage: Name: BridgeConst Prior Stage: NULL Construction Method: None Load Type: Dead Active: Yes | |
| 6 | Please repeat steps 2 through 5 to define all of the construction stages in the project. |  |
| 7 | In Staged Construction Analysis, when joints are activated they normally enter at the location that was initially given to them. Joints sometimes need to become active in a location relative to the deformed structure of the model, rather than in an exact position known ahead of time. The construction method option of construction stages specifies how to place a joint relative to the deformed location of other joints.
In Precast I Girder Bridges, deck formwork deforms and follows girder displacements. Therefore deck nodes should be constructed by shifting the node down to match the translational displacement of the girders nodes. This can be achieved with the Construction Method = Equal option of construction stages.

Follow the below steps to copy and paste all inputs from our data set.
| 1 | Navigate to Construction Stage under Loading on the tree view. |
| 2 | Copy Stage, Time Dependent and AASHTO N-3N from model inputs and paste into OpenBrIM. |
Copy the desired data with the automatic copy button in the upper left corner. Click on the first cell in and use the Ctrl+V shortcut to paste.  
If icon won’t appear, collapse page tree menu by clicking on arrow or using shortcut “[”.  While pasting large data, it would be handy to turn of Auto-refresh .
