Point to the home page of the Tension Member Design - Bolted to End Gusset module	Home page of the Tension Member Design - Bolted to End Gusset module opens.
Only narration	Let’s try to understand the design procedure by solving a sample design example.
Slide: Sample Design Example	Design a Tension Member with a bolted end connection The member carries a factored axial force of 600 kN
Slide: Sample Design Example	Perform an optimum design by adopting the following design specifications:
Slide: Sample Design Example	Section: Profile: Back to Back Channels Connection Location: Web Section Size: Most optimum Material Grade: E 250 (Fe 410 W)A Length: 3200 mm
Slide: Sample Design Example	End Connection: Connector: Type: Bolted Bolt Type: Bearing Bolt Diameter and Grade: Most optimum Gusset Plate: Thickness: Most optimum
Switch back to Osdag	Let us switch back to Osdag.
Only narration	I will start filling the Input Dock for our sample design.
Point toward the Input Dock	The Input Dock is on the left side of the GUI. We will use it to define the inputs for our sample design.
Click on the Section Profile drop-down menu	Click on the Section Profile drop-down menu.
Point to all the options in the list.	The available standard section profiles get listed.
Select Back to Back Channels	Select Back to Back Channels from the list.
Point towards the representative image.	The selected Section Profile can be confirmed by looking at the representative image.
Point towards the asterisk near Section Profile, Conn_Location, Length (mm)	The fields marked with an asterisk are mandatory user inputs.
Point towards blank fields	Other fields can simply be left without giving any input. In this case, Osdag will consider default inputs for performing the design.
Click on Conn_Location drop-down menu	Click on the Conn_Location drop-down menu.
Select Web	Select Web from the list.
Click on the Section Size drop-down menu	For the Section Size, we can either choose to perform the design with All or The Customized option.
Select the All option and hold the mouse to display its selection.	Selecting All will perform the design with all the sections in the database. The All option is used to perform an optimum design.
Only narration	We can also perform a design check by choosing specific sections. Desired sections can be selected from the Customized option.
Select the Customized option. Point to Customized window. Point to Available and Selected sections.	Let us select the Customized option. Customized window opens with Available and Selected sections.
Point toward the Selected sections in the Customized window.	Selected section displays the list of standard section sizes from the database.
Click on the cross field at the right corner	Now, close the Customized window.
Click on the Section Size drop-down menu	We will go back to the Section Size drop-down menu.
Select All option.	And, select All for our design example.
Point to Material.	Let us now specify the Material grade.
Click on the Material drop-down menu.	Click on the Material drop-down menu.
Scroll through the list	The list of standard material grades will open.
Point towards the Custom option.	Custom material properties can be defined and saved by using the Custom option.
Scroll up and select E 250 (Fe 410 W)A	I will select E 250 (Fe 410 W)A option.
Type 3200 in the Length text box.	Type the Length of the member as 3200 mm.
Point to Factored Loads.	Let us now define the Factored Loads.
Click in the Axial load textbox	The load values are defined using a textbox.
Type 600 in the text box.	Enter the value of Axial load as 600 kN.
Only narration	Let us now give input for the connector.
Click on the Bolt Diameter drop-down menu And click again on it to close the list	For the Bolt Diameter, we can choose between All or Customized.
Click on the Property Class drop-down menu , and click again on it to close the list	Similarly, for Property Class, we can choose between All or Customized.
Select All option and hold the mouse to show its selection.	Selecting All will give an optimum bolt design with respect to, Diameter Grade and Number of bolts.
Select the Customized option and hold the mouse to show its selection.	We can also check the design with a specific Bolt diameter and grade. Desired connectors can be specified by using the Customized option.
Click on the Diameter drop-down menu.	For an optimum bolt design we should select the All option.
Select All option.	I will select the All option.
Click on the Type drop-down menu.	The Type drop-down menu lists the standard types of bolts.
Select Bearing Bolt	Select Bearing Bolt from the menu.
