Please follow the instructions provided below to add influence surface. |
Table 3: VehicleInfuence 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.
|  |
| 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. |

| 2 | Copy General, and Centrifugal from model inputs and paste into OpenBrIM. | |
...
| 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. |
