Floor plan layout and loading plan of 7th floor are shown below. We are going to use following features while modeling on this floor.
→ Slab edge & slab piece
→ Slab opening
→ Copy from & Copy All.
→ Arbitrary & rectangular column
→ Show Tributary
→ Shear wall & analytical wall
→ Shear wall opening
→ Beam & analytical beam
→ Area loading & duplicate
→ Line loading
Go to 7th Floor → Overlay
Select 7th Floor linked drawing
Click Ok
Drawing Slab
Draw main slab edge polygon using slab edge command as explained before.
Draw slab pieces shown on reference drawings using slab piece command as expained before.
Enter the thicknesses of slab edge and slab pieces.
Enter clear covers of each slab object.
Enter elevation offset to slab pieces to adjust global elevations shown in the reference drawings.
Update the project.
Drawing Opening
DrawThere are openings
“Copy From” process is the same with copying columns or shear walls.with the same as roof openings, copy those openings from roof and draw the remaining openings.
Go to 7th Floor → Copy from
Select Opening objects to copy
Select Roof as source story
Click Select Graphically
Select the same openings
Press Enter
Go to Openings → Select Rectangular/Arbitrary
Draw openings
You can see openings by rotating 3D view after you update the project.
Drawing Columns
Go to 7th Floor → Overlay
Select 6th floor drawing → click OK
Now you see column belows of 7th floor.
Draw columns using commands appropriate to the column shape.
You can edit the width and depth or diameter of the columns from spreadsheet. The hold point remain fixed, and other points of the column will be repositioned according to depth and width. You can change the location of hold point from spreadsheet by changing Hold Point number.
.
You can see tributary areas calculated by AEC | BOLT Building Design Suite as shown below.
Click Show Tributary
Drawing Shear Walls
Draw shear walls and linked analytical walls
You already overlayed one lower floor’s reference drawings to see the columns&shear walls below.
Copy the same
shear walls from above floors
As explained before.
Go to 7th Floor → Copy From
Select Shear walls object to copy
Select Roof as source story
Click Select Graphically
Update the project
Draw the remaining shear walls
Go to Shear Walls
Click Shear Wall
Draw shear wall
Go to Analytical Walls
Click Analytical Wall
Draw analytical lines
You must draw a straight line from mid point of one edge to mid point of other edge of shear wall. If shear wall is not straight you must draw analytical walls for each directions of shear wall parts.
Enter thickness of each analytical wall
We will create an opening on shear wall for a door as shown below.
Go to analytical wall which the opening will be drawn
Click elevation view
Click Wall Opening → select rectangle shape
You must consider point locations on plan and elevation view.
Draw a rectangular opening with dimensions above.
Click Show Story to go back to plan view.
Drawing Beams
You can copy the same link beams from roof.
Go to 7th floor → Copy From
Select beams object to copy
Select Roof as source story
Click Copy All
Go to Beams
Click Draw Beam and draw remaining beams
You must draw
the beam between vertical support faces.
beams from face of the column or shear wall to face of column or shear wall
Enter the depth of the beam to spreadsheet
Edit the material property of the beam
Select the beam type
You must draw analytical beams for finite element model.
Go to Analytical Lines spreadsheet
Click Draw Analytical Beam
Draw the analytical beam line
Enter the width and depth of the analytical beam
While analytical beam line command is active, joint points shear walls are become visible. Drawing analytical beam lines using these joint will be more accurate for the generation of FE model.
If the line of analytical beam does not pass through the geometric center of the column, a secondary analytical line should be drawn between the column and analytical beam line.
You can start or end the line out of the beam polygon as long as middle point is inside the polygon borders.
When the analytical lines of beams or shear walls intersect, AEC | BOLT Building Design Suite creates break point joint on the intersection point.
Drawing Load Geometry
Go to Loads
Click Area
Draw slab edge polygon
Select superimposed dead load value according to the loading schedule as load case
Right click on the load in the spreadsheet
Click Duplicate
Select the live load value according to the loading schedule as load case of clone load are
Right click on the load in the spreadsheet
Click Duplicate again
Select type as line load
Select facade value according to the loading schedule as load case
Modelling of 7th floor is completed. Updated 3D view is shown below.
