Modelling of 3rd Floor

If you do not see the reference drawing of 3rd floor;

• Go to 3th floor → Overlay

• Select 3th floor linked drawing → Click OK

• Go to 3rd Floor → Copy From

• Select Slabs (and openings) to copy

• Select 4th floor as source

• Click Copy All

Or

• Draw main slab by using slab edge command

• Draw slab pieces using slab piece command

• Edit offset, thickness and clear cover properties of each slab object

All the openings in 4th floor are the same with 3rd floor you can copy them from above. Draw the extra openings shown below.

• Go to 3rd Floor → Copy From

• Select openings to copy

• Select 4th floor as source

• Click Copy All

Then

• Draw extra openings using Rectangular command.

• Go to 3rd Floor → Overlay

• Select 2nd floor linked drawing

• Unselect 3rd floor linked drawing

• Now you see the columns below for 3rd floor.

All the columns except the walking column are the same with the 4th floor. But AEC | BOLT Building Design Suite allows you to edit the walking column section easily.

• Click Copy From

• Select Columns (and shear walls) to copy

• Select 6th or 5th floor as source story

• Click Copy All

Now you should edit the walking column section and draw the circular columns.

• Go to 3rd Floor → Copy From

• Select Shear walls object to copy

• Select 4th floor 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

• Go to 3rd floor → Copy From

• Select beams object to copy

• Select 4th 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.

• Go to 3rd Floor → Copy From

• Select Shear walls object to copy

• Select 4th floor as source story

• Click Copy All

• Update the project

Or

• 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.
