Floor plan layout and loading plan of 6th floor are shown below. We are going to use following features while modeling on this floor.
→ Slab edge & slab piece
→ Slab opening
→ Copy from & Select Graphically.
→ Arbitrary & rectangular column
→ Show Tributary
→ Shear wall & analytical wall
→ Shear wall opening
→ Beam & analytical beam
→ Area loading
→ Duplicate
→ Line loading
Go to 6th Floor → Overlay
Select 6th Floor linked drawing
Click Ok
Drawing Slab
Slab egde edge geometry is the same with 7th floor. You can copy from 7th floor or draw slab edge manually.
.
Or
Copy the same slab edge and slab pieces from the floors above.
Go to 6th Floor → Click Copy From
Select slabs and select 7th floor
Click Select Graphically
Select the slab edge and slab pieces
Press Enter
You can copy multiple (such as openings) objects at the same time.
Draw the remaining slab pieces with slab piece button.
Or
Draw slab edge using slab edge command.
Draw all the slab pieces using slab piece command
Drawing Opening
Draw openings as explained before or you can copy openings which are the same from roof.
The openings are the same with the7th floor.You can copy all the openings from above or draw them manually.
Go to 7th Floor → Copy from
Select Opening objects to copy
Select 7th as source story
Click Copy All
Or
Go to Openings → Select Rectangular/Arbitrary
Draw openings
Drawing Columns
Since 6th and 5th floors are similar, floor plan is typical for these stories. Thus there is no need to overlay one lower floor plan to see the columns below.
Also columns of 7th floor are continue in 6th floor. You can copy columns (and shear walls) from 7th floor.
Go to 6th floor → Copy From
Select columns (and shear walls)
Select 7th Floor
Click Copy All
Or you can draw columns manually.
Draw rectangular columns by using rectangular column command that explained before.
Draw arbitrary and rotated rectangular columns by using arbitrary column command that explained before.
Drawing Shear Walls
You can copy the shear walls from 7th floor if you did not copy with the columns or you can draw shear walls manually.
Go to 7th Floor → Copy From
Select Shear walls object to copy
Select Roof as source story
Click Copy All
Update the project
Or draw the shear walls.
Go to Shear
Draw shear walls and linked analytical walls
or
Copy the same ones from above floors
As explained before.
Walls
Click Shear Wall
Draw shear wall
Select the material of the 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
Do not forget to draw shear wall opening which has the same dimensions with 7th floor.
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 beams from 7th floors or you can draw the beams manually.
Go to 6th floor → Copy From
Click Draw Beam and draw the beam between vertical support faces.
Or
Copy the beams from 7th floor as explained before.Select beams object to copy
Select 7th as source story
Click Copy All
When you copy beams, analytical beams are also copied.
Or
Go to Beams spreadsheet
Click Draw Beam
Draw beams from face of column/shear wall to face of column/shear wall
Enter the depth of the Beam
Select the material of the beam
Select beam type
If you draw beam manually, do not forget to draw analytical beams.
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 joints will be more accurate for the generation of FE model.
When you copy beams, analytical beams are also copied.
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 residential/terrace/corridor areas according to the loading schedule
You will add superimposed dead loads and live loads to the same areas but you do not need to draw again.
Right click on the areas in the spreadsheet
Duplicate areas
Select load cases appropriate to the loading schedule
Click Line
Draw facade load lines and parapet load lines
Select load cases of the line loads.
You can see the loading geometry by right clicking and selecting in the AutoCAD.
Modelling of 6th floor is completed. Updated 3D view is shown below.
