To model beams and bracings for industrial steel structures using TSD

1.Aim:

To create beam properties for First floor and model the beams by using TSD.

Procedure:

• Open the TSD file which was modelled in the earlier challenges.
• In the structure window click first floor.
• 
• Click 3D in the status bar to view the 3D view of first floor.
• 
• To create beams in first floor:
• Create a new beam property for Grid C and D which helps to support crane movement.
• 
• 
• Go to first floor plan and connect the main beam from column to column with the created property.
• 
• To create secondary beams:
• Go to Ground level and create construction lines for creating secondary beams with the created property.
• 
• Create secondary beam as required by referring the floor plan.
• 
• Go to first floor and follow the above procedure and create construction lines and secondary beams as required.
• 
• Result:
• Click 3D icon in the bottom right corner to view the 3D view of a particular floor.
• Main beam and secondary beams are created in the first floor.
• 

2. Aim:

To create rafter beam on second floor as roof and moment frame action in one direction and add bracings at locations as per the design intent

Procedure:

• With above created model, go to Top of roof beam level
• Click Model -> Beam
• Select the beam property as SB1 which is used as main beam in ground level and connect the columns as shown below.
• 
• Creating frames:
• Go to Model -> Frames and pick grinds one by one
• 
• Similarly create the frame on other direction.
• Expand the frame option in structure window to view the created frames
• 
• Creating Roof beam:
• Go to FRM1 and create construction line at the middle
• 
• Go to Home ->Manage property sets. And create beam property for roof beams
• 
• Go to Model -> Beam and select the above created beam as rafter beam and column to the construction line on both sides
• 
• Select the rafter beams in 3D view and Go to Edit -> Copy
• 
• Pick a reference point and place it to the adjacent columns.
• 
• To have moment release on the rafter frame, double click on the frame and give following settings.
• 
• Click ok and continue the same procedure for all other rafter beams.
• To create bracing:
• Select FRM C 2D view
• Go to Home -> Manage property sets -> New -> Members -> Steel bracing and give following settings
• 
• Go to Model -> X Brace and select the property as BR.1
• Pick corner 4 points to connect the bracing.
• Adjust the major snap level according to the design
• 
• Similarly, do it on Grid G in FRM G 2D
• 
• To create Ridge beam:
• Go to Home -> Manage property sets -> New -> Members -> Steel beam and give following settings
• Go to Home -> Manage property sets -> New -> Members -> Steel bracing and give following settings
• 
• 
• To create bracing on the roof panel:
• Go to Model -> Brace and pick the center point of the section of roof panel and connect it to the other end of the same section.
• 
• Then select X Brace and create X brace as shown below.
• 
• Repeat it to the other panels
• 
• To create wall panel:
• Go to Model -> wall panel
• Select 5 corner points between columns.
• 
• Repeat the same procedure to the other area to apply wall panel.
• 
• To model Roof panel:
• Go to Model -> Roof panel.
• In 3D view click the corner points and create roof panel on the roof.
• 
• Repeat it throughout the roof.
• 
• Result:
• Hence the beams, bracings, wall panel, roof panel are all have been model by following the above steps.
• 3D View:
• Click 3D Structure to view the overall 3D view of the model
• 
• Solver view:
• Click solver icon to view the nodes
• 
• Validate:
• Click Model ->Validate to check the model.
