Modelling of 6th Floor

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 edge geometry is the same with 7th floor. You can copy from 7th floor or draw slab edge manually.

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

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.
Draw arbitrary and rotated rectangular columns by using arbitrary column.

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 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
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.

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.
