Slide: Title Slide	Welcome to the spoken tutorial on Performing a design check in Osdag.
Slide: Learning Objectives	In this tutorial, we will learn how to, Perform a design check Interpret the log messages Rectify unsafe designs using log messages Arrive at a safe design using log messages.
Slide: System Requirements	To record this tutorial, I am using: Windows 11 Operating System, and Osdag v2021.02.a.a12f
Slide: Pre-requisites https://spoken-tutorial.org	To follow this tutorial you should have, Osdag installed on your system Basic knowledge of structural steel design If not please access the prerequisite tutorials available on this website.
Only narration	The user interface of Osdag for Ubuntu Linux, and Windows is the same.
Only narration	In this tutorial, We will solve a sample design example to demonstrate Scenario 2.
Slide: Sample Design Example	Design a Tension Member with a bolted end connection The member carries a factored axial force of 500 kN Let’s perform a design check by adopting the given design specifications: Section: Profile: Back to Back Angles Connection Location: Long Leg Section Size: 120x120x12 Material Grade: E 250 (Fe 410 W)A Length: 3200 mm
Slide: Sample Design Example	End Connection: Connector: Type: Bolted Diameter: 16, 20 Bolt Type: Bearing Bolt Grade: 4.8, 5.8, 6.8 Gusset Plate: Thickness: 16 mm

Point toward the < button	The third button deselects a single section from the Selected list. It sends the section back to the Available list.
Point toward the << button	And, the fourth button deselects all the sections at once. It sends all the sections back to the Available list.
Click on the << button	Click on the fourth button to unselect all the sections at once.
Point toward the list of Available sections in the Customized window.	We can select the desired section from the list of Available sections.
Scroll down multiple times in the list of Available sections in the Customized window.	Scroll down the list of Available sections to locate 120x120x12.
Point toward 120x120x12	We have located the desired section.
Point to the section.	There are two ways to select a section: We can either double-click on a particular section to select it right away.
Click on 120x120x12	Another way is to click on the desired section to choose it.
Click on the > button	Then click the second button to add it to the list of Selected sections.
Point toward 120x120x12 in the Selected sections list	We can now see the section listed under the Selected sections on the right.
Click on the Submit button	Click on the Submit button below to confirm and exit.
Only narration	Let us now specify the Material Grade.
Click on the Material drop-down menu and Select E 250 (Fe 410 W)A	Click on the Material drop-down menu and select E 250 (Fe 410 W)A.
Type 3200	Enter the Length of the member as 3200 mm.
Factored Loads.	Let us now define the Factored Loads.
Type 500	Enter the value of Axial load as 500 kilo newton.
Only narration	Let us now give input for the connector.
Click on the Diameter drop-down menu and Select Customized.	Click on the Diameter drop-down menu, and Select Customized.
Point to the Selected list. Move using the << double arrow button.	Here we see all the diameters in the Selected list. Users can move the list to the Available section.
Point toward the Available list	The standard Available bolt diameters are listed on the left.
Point to the list	Next, we will select the desired diameters from the list.
Press Ctrl and click on 16 and 20.	Press the Ctrl key and click on 16 and 20 to select multiple diameters from the list.
Click on the > button	Then click on the second button to add them to the list of Selected diameters.
Click on the Submit button	Click on the Submit button below to confirm and exit.
Click on the Type drop-down menu >> select Bearing Bolt .	For the bolt Type, select Bearing Bolt.
Click on the Property Class drop-down menu	Click on the Property Class drop-down menu, and Select Customized.
Point toward the Selected list	The standard available bolt grades are listed on the right.
Cursor near Selected.	All the grades are selected by default in the Customized option. Let us now deselect the unwanted grades from this list.
