Working with reinforcement tools - Part 3

00:04

After completing this lesson, you'll be able to add path reinforcement and add varying reinforcement.

00:12

The objective domains covered are 1.1h work with reinforcement tools, and 4.2a develop and customize schedules.

00:21

Path reinforcement is very useful when you need to add U bars or L bars along a path.

00:27

For example, a series of slab edges could be used by the Path Reinforcement Command to populate U bars around the perimeter.

00:34

Path reinforcement can also incorporate curves.

00:38

The path reinforcement, by default, is grouped within a path system,

00:43

but you have the option of removing this, which creates separate rebar sets that you can then manipulate as usual.

00:50

Varying reinforcement is useful in situations where the formwork is skewed, or the elements 'section size is continually changing.

00:58

In the examples below, you can see two layers of reinforcement added with varying range.

01:03

The stirrups within the type of beam are varying along the length.

01:08

Go ahead and open up the model 015-Work with Reinforcement Tools.

01:13

The model opens in 04-Fourth Floor Plan.

01:18

Before we start creating reinforcement bar, we're first going to open a 3D view and tile these views side by side.

01:25

In the project browser, go ahead and open up the 3D view.

01:31

Note, we have the two tabs open at the top.

01:34

We now need to tie all these windows side by side.

01:38

Let's use a Revit keyboard shortcut "WT".

01:43

And also, we might want to initially zoom all.

01:46

So, again, we could use a keyboard cable shortcut "ZI".

01:51

OK, so let's now begin by looking at path reinforcement.

01:56

We will zoom up on our fourth floor.

01:60

Our intention here is to add some path reinforcement around the edge of this slab.

02:06

To do this, on the Structure ribbon, select Path.

02:11

A valid host for path reinforcement is a structural floor or a wall.

02:16

So, in this case, we'll select our structural floor.

02:21

On the context ribbon, the default is to create lines around our slab.

02:26

But, of course, we could also use Pick Lines.

02:34

We have the option of flipping if the reinforcement is on the wrong side of the slab.

02:41

In the Properties palette, we can then configure our settings.

02:44

So, you'll notice here, the layout rule is Maximum Spacing.

02:49

Here we're going to use a bar spacing of 10 inches.

02:54

Our primary bar type will be bar #3, our bar length is going be 18 inches, and our primary shape is 17.

03:04

Let's go ahead and select Finish Edit Mode.

03:09

Now, if we see them up on the 3D view, we might notice that the U bars are in the wrong orientation.

03:16

So, here, we can select our U bar, and we can press the "Spacebar" to orientate these.

03:24

Another potential issue will be where the U bars clash in the corner.

03:29

Now, at the minute, this is a path reinforcement element.

03:33

If I select that element, on the context ribbon, I can Remove the Path System.

03:39

This will then break down the path system into separate ranges that I can then manually take control of.

03:49

OK, so our path reinforcement is now complete.

03:53

Let's now move on to some varying range rebar.

03:57

In the fourth floor, we'll note here that we have a single reinforcement bar modeled.

04:03

Our intention here is to create a rebar set for this so it distributes it along the slab.

04:09

But we want the bar to remain the same length but orientated to this edge of the slab.

04:15

Now, on the context ribbon, you'll note that the varying range rebar set is activated.

04:20

I'm just going to temporarily deactivate this.

04:23

I then go ahead and create a rebar set.

04:27

Notice here that Revit then keeps the bar parallel to the slab edge.

04:33

However, if I go ahead and select a Varying Rebar Set, you'll now notice that the bar is skewed and following the skewed slab edge.

04:44

Let's now take another look at varying range rebar on a retaining wall structure.

04:50

I'm going to close down the fourth floor, and in the project browser, let's go ahead and open Section 1.

04:58

Once again, we'll tile our views, so we can use a keyboard shortcut "WT".

05:05

And we'll see them up on our retaining wall structure.

05:09

So, of course, you'll notice here that the retaining wall structure in this particular example here is tapering.

05:16

The section that we're looking at here is cut at the smaller end of the retaining wall.

05:20

We're going to create a straight bar in this sectional view,

05:24

and then use the varying range rebar to create a varying range rebar set where the bar #8 will change.

05:31

Now, you may remember that the reinforcement settings will control how that bar is marked.

05:36

Let's take another look at this.

05:39

In the Reinforcement dropdown, let's select Reinforcement Settings.

05:45

We'll select a Varying Rebar Set.

05:48

And you'll notice here that we're going to use Number Bars as a Whole, and we've got the suffix "a".

05:53

So, what's going to happen here is we'll have the primary bar mark. It may be bar mark 5, for example.

05:59

And then we might see five 5a, 5b, 5c, et cetera.

06:06

OK. Let's first model our reinforcement bar.

06:11

Let's start by selecting Rebar.

06:15

The placement method currently is set to Rebar.

06:19

In this example, I'm going to use Sketch Rebar.

06:23

We'll go ahead and select our wall.

06:28

And here we can sketch our reinforcement bar.

06:35

Once we finish sketching, we can select Finish Edit Mode.

06:41

If I select that newly sketched reinforcement bar, you'll note in the Properties palette,

06:46

the Revit has also detected the shape; in this case, 00.

06:54

Let's now take a look at that reinforcement bar in 3D.

06:58

First, we'll set the View Visibility State.

07:01

So, in the Properties palette, we can select View Visibility State and then "Edit".

07:07

And here in our 3D view, we want to make this View Unobscured and View as a Solid.

07:16

And here is our reinforcement bar.

07:19

On the context ribbon, let's now create a rebar set from this.

07:23

So, again here, we'll use maximum spacing.

07:26

We'll have a spacing initially of 10 inches.

07:30

And you'll notice now that the rebar's length is constant across the tapered wall.

07:35

However, if we go ahead and select Varying Rebar Set, what we can now do is use the shape handle to adjust the reinforcement bars.

07:47

Finally, let's take a look at the schedule.

07:50

In order for this to appear in the schedule, we need to give it the correct partition.

07:55

In the Properties palette, typing "DWG 01".

08:02

In the project browser, let's go ahead and open up DWG01 Rebar Schedule.

08:08

And you'll now notice that we've got our host mark "RW01".

08:12

So, you now see that we have the bar mark 1a, 1b, 1c and so on.

08:18

This was due to the fact that we've changed our reinforcement settings.

08:22

And also in the schedule, we've combined two parameters together.

08:25

Let's take a brief look at that.

08:27

In the properties palette, let's edit the Fields.

08:32

Note in here that I have something called my Bar Mark,

08:36

but if I come down and edit this, you'll now notice that this is actually comprised of two parameters.

08:41

You can see here I have the rebar number and then also the rebar number suffix, which is the a, b, c, d.

08:51

OK, so our schedule is now complete.
