Please follow the instructions provided below to add design lanes.

Table1: Design Lane

1

To affect live loads on your bridge, you must activate them according to your standard. Note that vehicle data definitions are provided before the design lane definitions.
However, if you begin by defining a Design Lane, OpenBrIM will automatically assign the vehicle data.

2

Navigate to Loads > Influence Surface Based LL/BR/CE > Design Lane

3

Click three-dots icon on Name and click Import Design Lane to import design lanes.

4

You can import 'Design Lanes' with parameters from the OpenBrIM core memory, as in the figure.

Import all of the Design Lines indicated by the red arrow (except HL93AndLane_Deflection2)

5

These three parameters should be separated into substructure and superstructure categories. This means that they must be imported twice, with different names, as they take different coefficients.

  • HL93AndLane_LL(sub)

  • HL93TandemTruckAndLane_LL(sub)

  • HL93TwoTrucksAndLane_LL(sub)

We have defined 14 Design Lanes in total.

6

The incoming lane width [ft] data will remain constant for this project.
And set the vehicle and lane edge [ft] to “2”

7

Navigate to Vehicles tab.

The data in the Vehicles 1 column is automatically set when we define the Design Line.

8

To set the Vehicle 1 Impact factor for the loads defined in the infrastructure, refer to the values provided red rectangle in the figure and apply them accordingly.

9

Navigate "Vehicle Placement Setting" tabs.

As shown in the figure, enter the "Max Vehicle Spacing (Back to Front)" values of 50 ft for the lines with "Adjacent Span Placement" set to "Yes."

10

Keep the values in the "Lane Load" and "Lane Placement Setting" tabs with their respective "default" values.

Follow the below steps to copy and paste all inputs from our data set.

1

Navigate to Design Lane under Inf. Surface Based LL/BR/CE on the tree view.

2

Copy Properties, Vehicles, Lane Load, Vehicle Placement Settings, and Lane Placement Settings from model inputs and paste into OpenBrIM.

Please follow the instructions provided below to add vehicle definitions.

1

Navigate to Loads > Influence Surface Based LL/BR/CE > Vehicle

2

Click three-dots icon on Name and click Import Vehicle.

3

You can use the OpenBrIM library to import the live load status of vehicles according to various standards.

4

All of the vehicle data is automatically imported once the Design Lane has been imported.

1

Navigate to Vehicle under Live Load on the tree view.

2

Copy related Dara from model inputs and paste into OpenBrIM.

Please follow the instructions provided below to add influence surface.

1

Navigate to Loads > Influence Surface Based LL/BR/CE > Infuence Surface

2

Click three-dots icon on Stage and click Select.

3

After the completion of pavement on a bridge and highway, the forces exerted by vehicles on the pavement include live load, load at braking, and centripetal force. These three states must be assigned to stages in the 'Influence Surface'.

4

Set the Stage data as in the figure.

Then enter the name of the “Influence Surface (loads)” that have been entered.

5

Click three-dots icon on Roadway.

Assign the roadway R1 which was defined in the previous steps, to each (Influence Surface) load in the project.

6

Each defined 'Influence Surface' load has a category.

Assign the appropriate categories to them.

7

For each (Influence Surface) load, each impact surface parameter values as follows.

  • Unit Load Spacing Long. [in]: 360

  • Unit Load Spacing Trans. [in]: 72

8

Navigate to Centrifugal tab.

Enter Highway Design Speed [ft/second] data as 58.7

9

Click on the three-dots icon on Centrifugal Force Factor and set it to 'Other Than Fatigue (1.33)' for the “ISCentr” load.

Follow the below steps to copy and paste all inputs from our data set.

1

Navigate to Influence Surface under Live Load on the tree view.

2

Copy General, and Centrifugal from model inputs and paste into OpenBrIM.

Please follow the instructions provided below to define live load cases.

1

Navigate to Loads > Influence Surface Based LL/BR/CE > Live Load Case

2

In this step, we define the "Live Load Cases" for which limit states will be used.

3

Select the (Influence Surface) loads that were defined in the previous step for the live load cases you wish to define.

Next enter the names of the defined live load cases.

4

Set the "Max for Stress Range (Fatigue)" parameter to "Yes" for the "LLFatCase" live load case.

5

Navigate Design Lanes tab.

6

To perform the design calculation, vehicle scenarios must be created on the roadway.

To perform this, vehicle scenarios need to be applied to the 'Live Load Cases' that were defined previous step.

 

Click three-dots icon on Design Line Option cell and click Select.

 

 

Assign the design lanes to the 'Design Lane Options' as in the figure.

Follow the below steps to copy and paste all inputs from our data set.

1

Navigate to Live Load Case under Live Load on the tree view.

2

Copy General and Design Lanes from model inputs and paste into OpenBrIM.

 Quick Tip: Copy inputs to 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 .
