Pile caps are placed with the isolated foundation. Command,
00:07
the pile cap can be placed separately to the piling
00:10
or an assembly of piles and pile caps can be placed
00:14
rev it contains several pile cap and pile families ready for your use
00:19
rather than manually assembled a pile cap and piles for regular arrangements,
00:23
you can place a preassembled family.
00:26
The pile cap contains nested families for the piles.
00:29
If the pile families are set to shed and they're nested,
00:32
you can schedule it and tag the piles separately.
00:35
A grade beam is treated differently to a wall foundation
00:39
and is typically designed for bending due to these conditions.
00:42
It is recommended that you use a beam
00:45
to differentiate between substructure and superstructure.
00:48
You can add type comments and classifications that can
00:51
help you filter these elements within schedules and views.
00:56
We're going to start by placing out pile caps with nested piles.
01:01
Let's begin by opening up the structural plan to a foundation
01:05
in the project browser under structural plans. Double click on top of foundation.
01:11
We're going to begin by placing some foundations on grid three.
01:15
We need foundations at B three C three and D three
01:20
the pile cap and nested piles will also be placed with the isolated foundation tool
01:26
to launch this command. We'll select the structure ribbon
01:29
and on the structure ribbon, we'll select isolated foundation
01:33
in the properties pallet in the type selector.
01:36
You'll note here that we have a number of pile caps and piles loaded in.
01:40
These particular families are nested families.
01:43
So we have pile caps and inside those pile caps,
01:46
we have nested a number of different piles.
01:50
We're going to begin by placing out pile cap for pile.
01:53
So let's go ahead and select this family here
01:57
and we'll now place out this family on the intersection of the grids.
02:01
So I'm going to start at B three
02:03
and notice here if I hover my cursor, I get nearest to nearest.
02:07
When I see this, I can simply left, click to place down my pile cap and piles.
02:12
I'll do the same on C three
02:14
and D three
02:17
on grid 2.1. We're required to use single pile pile
02:20
caps
02:22
to set these in the properties paddock
02:24
in the type selector. Let's go ahead and select pile cap one pile.
02:29
Now, rather than placing these manually
02:32
on the context ribbon, I'm going to select at columns.
02:36
I can then make a selection set of these three concrete columns.
02:40
And of course, you'll now notice previewed. We have three foundations.
02:45
This is just a preview. So to finalize the placement of these
02:48
on the context ribbon, we can click finish
02:52
on grid two. We're now going to place pile cap two pile.
02:57
So again in the properties pad it in the type selector,
02:60
we'll change our selection from pile cap, one pile to pile cap two pile.
03:05
As we move our cursor across,
03:06
you can see here that we probably need to rotate this pile cap to do that.
03:10
I'll press the space bar
03:13
and now I can again snap to the
03:15
grid intersections where I'm seeing nearest to nearest
03:17
and then place down three more foundations.
03:21
I'm now going to place the same pile cap along grid one
03:25
to do this again, I'll use the at columns tool on the context ribbon.
03:30
I'll make a selection set with these three columns here
03:33
and you can see here the orientation of the pile caps is incorrect
03:36
to rotate them.
03:37
I can simply press the space bar and of course, they'd all rotate together.
03:42
Once again, this is just a simple preview.
03:45
So to find the nicer placement on the context ribbon,
03:48
we'll go ahead and select finish.
03:50
Finally, we're required to place a three pile pile cap at this intersection here.
03:55
So once again, in the properties padded in the type selector, we'll choose pile cap,
04:00
three pile,
04:03
I need to rotate the pile cap so I can press the space bar twice. In this case,
04:07
I can snap this pile cap to the intersection of the
04:10
two grids and left click when I see nearest the nearest.
04:14
OK. So that finalizes the placement of pile caps
04:17
to release the command. We'll go ahead and select, modify on the context ribbon
04:22
to review the design. We'll go ahead and select 3D foundations view.
04:27
We can now see in 3D that we have our pile caps and piles created
04:33
because these are nested families.
04:35
I can move over one of these piles here and to select the pile,
04:39
I can press the tab key on the keyboard and
04:41
then make a single selection of this single pile.
04:44
This is possible because the pile is set up to be shared.
04:48
And when the shared property is set, it becomes a sub component that is selectable.
04:53
If it's selectable, it means I can tag it and schedule it.
04:58
You'll notice without using the tab key.
04:59
When I make a selection set, the entire family will be selected.
05:03
But again, to make a selection set of a specific pile, I can pause my cursor over that,
05:08
press the tab key once and then make my selection.
05:12
Ok. So let's now place our grade beams
05:15
to do this. We'll switch back to the top of foundation plan
05:19
and the grade beams are created with the beam tool
05:22
to launch the beam tool on the structure ribbon, we'll select beam
05:27
in the properties pad it in the type selector.
05:29
Just ensure that you have concrete rectangular beam 24 inch by 30 inch selected
05:36
on the options bar. We're going to check that we have line enabled
05:40
and also we're not going to tag these on placements.
05:43
So you'll notice this isn't selected at the minute
05:45
and now we're ready to start to place down our grade beams.
05:49
I'm going to begin by drawing a grade beam from the mid point of this column here
05:53
to the midpoint of the column. Here
05:56
I can then continue
05:57
by selecting further midpoints.
06:00
I've been able to model a consecutive set of grade beams
06:03
because the chain option is switched on on the options bar.
06:07
I'm now going to deactivate the chain option.
06:10
And I'm going to draw one single grade beam to this next position here
06:15
because chains now off,
06:16
I can then go through and select the midpoints on these
06:19
column intersections and then place out the remaining grade beams.
06:29
Ok. So the grade beams are now complete.
06:33
Now,
06:33
even though we've modeled the grade beams from the midpoint
06:35
of the column to the midpoint of the column,
06:38
they will in fact be cut back to the faces of each of the pile caps.
06:42
To check this, we'll go ahead and select, modify to release the beam command.
06:46
And now if I select one of these beams,
06:49
you'll notice that it's cutting back to the edge of the pile caps.
06:52
Of course, we can inspect this in the 3D view.
06:55
So we'll switch to the 3D foundation view
06:58
and here you can now see that gray beam is selected
07:01
and in fact, it's not going to the center of the pile cap,
07:03
it's cut back to the pile cap faces.
07:09
Ok.
07:10
So to summarize,
07:11
we've been able to place out pile caps and piles in a single operation,
07:16
the piles are shared,
07:17
which means that we can schedule and tag those
07:19
and select them independently of the pile cap family.
07:23
We've also then placed out grade beams between the pile centers
07:27
and the grade beams have then cut back to the pile cap faces.
07:31
We've used the beam tool so we can use
07:33
an analysis method to calculate the bending moments.
