Author: Monika Soni (script), Anandajith TS (recording)
Keywords: osdag, member design, connection design, steel design optimisation, tension member, unsafe design, log messages, error, warning, info, video tutorial.
Visual Cue | Narration |
Slide: Title Slide | Welcome to the spoken tutorial on Handling unsafe designs in Osdag. |
Slide: Learning Objectives | In this tutorial, we will learn how to,
|
Slide: System Requirements | To record this tutorial, I am using,
|
Slide: Pre-requisites | To follow this tutorial you should have,
The prerequisite tutorials are available on this website. |
Only narration | The user interface of Osdag for Ubuntu Linux, and for Windows is the same.
|
Point to the home page of the Tension Member Design >>
Select Bolted to End Gusset module |
Let us switch to the home page of Tension Member Design.
Select Bolted to End Gusset module. |
Point toward the Input Dock fields | I have loaded the Logs underscore sample underscore design dot OSI file. |
Only narration | Please pause the tutorial and load the input file. |
Click on the Design button. | Click on the Design button below to perform the design. |
Only narration | Osdag carries out the design. |
Point toward the CAD window | Note that the CAD window is inactive. |
Point toward the Output Dock | The Output Dock is not populated with the output values. |
Only narration | This is because the design is complete but unsafe. |
Point to the Output Dock. | Let us disable the Output Dock to maximise the log message window. |
Click on the close Output Dock button | Click on the close button at the top right corner of the Output Dock. |
Point toward the Log messages | We see the colour-coded log messages pertaining to the design. |
Highlight the timestamp in the log messages | The log messages are marked with a timestamp for the reference of the users. |
Highlight ERROR message | The ERROR message is marked in red and indicates the status of the design.
|
Only narration | Let us rectify the design using the log messages and arrive at a safe design solution. |
Point to the message in blue colour. | The WARNING messages are marked in blue colour. |
Highlight the WARNING message. | The WARNING message gives a warning pertaining to a specific design check. |
Highlight the WARNING message | The WARNING message reads, that the tension force exceeds the tension capacity. |
Point to the message. | This means that the force exceeds the member capacity in tension. |
Point to the message. | The INFO messages are marked in green colour. |
Highlight the first INFO message | The INFO message gives suggestions to rectify the unsafe design. |
Highlight the last INFO message | It also suggests where the design check or a trial design has ended. |
Highlight the first INFO message | The INFO message reads, ‘Define members with a higher cross sectional area’. |
Highlight 80 x 80 x 8 in the message. | This means we have to define a section with an area greater than 80 x 80 x 8. |
Only narration | Let us define a new section. |
Click on the Section Size drop-down menu | Click on the Section Size drop-down menu and select Customized. |
Double-click on 80 x 80 x 8 in the Selected list | Double-click on 80 x 80 x 8 in the Selected list to deselect the section. |
Scroll down in the Available list and double click on 90 x 90 x 8. | Now, scroll down in the Available list.
|
Click on the Submit button. | Click on the Submit button below to confirm and exit. |
Click on the Design button | Then, click on the Design button below to perform the design. |
Point to the messages. | We see ERROR and WARNING messages again, as the design is still unsafe. |
Highlight the WARNING message | The WARNING message reads, that the tension force exceeds the tension capacity. |
Point to the messages. | Here, the sectional area is satisfied but the plate thickness is less. |
Only narration | Let us define a thicker gusset plate. |
Click on the Thickness drop-down menu | Click on the Thickness drop-down menu and select Customized. |
Double-click on 12 in the Selected list | Double-click on 12 in the Selected list to deselect the plate. |
From the Available list double-click on 16 | Now, from the Available list double-click on 16 to select the plate. |
Click on the Submit button. | Click on the Submit button below to confirm and exit. |
Click on the Design button. | Again, click on Design button below to perform the design. |
Only narration | Osdag carries out the design. |
Highlight the fourth INFO message | The INFO message reads, ‘Overall bolted tension member design is safe’. |
Only narration | This means that the design is complete and successful. |
Highlight the third INFO message | If there is scope to optimize the design, Osdag will display additional INFO messages. |
Only narration | But, this does not mean that the design is unsafe. |
Only narration | Optimum design can be achieved by defining more inputs for the section, connectors, etc. |
Only narration | This brings us to the end of this tutorial.
