External Diaphragm [EX1-STG]
Please follow the instructions provided below to create External Diapgrahm.
1 | Navigate to Bracing > External Diaphragm Several structural elements are used to ensure that the two Tub Girders work together structurally, and one of these elements is the "External Diaphragm”. |
|
2 | Click three-dots icon on Girders cell and pick the two Tub Girders (G1 & G2) between which the External Diaphragm will be placed. | |
3 | Define 5 External Diaphragms with the following inputs. |
|
4 | Also Skew Angle value is 0. | |
5 | Since our project has 4 pier-end points, assign the "Pier-End" type to the External Diaphragm for the first 4 rows. Assign the "Intermediate" type to the External Diaphragm for the last row.
|
|
6 | Click three-dots icon on Select Pier/End cell and pick location as in the figure.
| |
7 | Enter the following data for Offset from Pier/End [ft] as in the figure |
|
8 | Click three-dots icon on Material cell and assign the material type of all external diaphragms to A709_50W. | |
9 | You can make adjustments to the "Section Details" and "Stiffener" tabs if you wish. |
1 | Navigate to External Diaphragm under Bracing on the tree view. |
2 | Copy Location, Section Details and 3D Details from model inputs and paste into OpenBrIM. |
The External Diaphragm that have been created are illustrated below.
