Publish civil structures

00:04

We will be looking at how we can progress our conceptual design.

00:09

So the first thing that may be useful is to share our conceptual design

00:13

so that other team members can utilize the work that we've done.

00:19

We can use the published civil structures function

00:22

to produce data that can be shared to civil 3d

00:25

and also rev it as we will see in later videos.

00:31

This enables the road designers to make use of the conceptual design

00:35

and progress their work in parallel to the bridge team.

00:39

Once in civil 3d,

00:41

the designer will configure the exchange

00:43

settings to ensure consistency with existing standards

00:46

and then browse to the shared data

00:48

that will then be introduced to the civil 3D drawing.

00:52

This new data includes the surfaces, corridor,

00:56

road assemblies, as well as the bridge components and the road alignment.

01:07

The bridge design can be progressed beyond that created at the conceptual

01:11

stage by applying modifications to the main components of the bridge.

01:15

Having selected the bridge and made the deck visible,

01:18

we can change the deck properties by altering the values in the panel.

01:22

In this case, both for debt depth and also for continuity,

01:27

which will also affect the bridge girders.

01:32

The bridge girders can also be modified for both number and type

01:37

and also four dimensional changes.

01:39

In this case,

01:40

we are exploring the possibility of changing

01:42

the girders from a precast concrete arrangement

01:46

to a dual steel box girder solution.

01:48

Once the girders have been correctly configured for a single span,

01:52

that arrangement can then be applied instantly to the rest of the ridge.

01:59

Once the goa

01:60

system has been changed,

02:01

the designer could then look at modifications to the bridge pier arrangement.

02:08

As with all bridge components,

02:10

the pier can be modified as before by entering values in the panel.

02:14

We can see here that the designer is making some significant changes

02:18

to the pier by firstly changing the type and number of columns

02:22

and then increasing both the diameter of the columns

02:25

and the depth of the pier cap.

02:28

Once those changes have been completed,

02:30

the designer can instantly replicate that peer arrangement

02:34

to the other peers within the bridge.

02:36

As the girder arrangement has been changed to the

02:39

steel box girder type with longer span capability.

02:43

It is feasible for the designer to reduce the number of peers to better reflect this.

02:51

The bridge designer may also need to adjust the bridge abutments.

02:54

The designer follows the same process as with other bridge components

02:58

by selecting the component and picking a new part from the available list.

03:03

The default abutment is modeled

03:05

and the designer can then make the necessary changes

03:08

such as in this case with par number and length.

03:14

Lastly,

03:15

the designer will make changes to the foundations all

03:17

as before until a suitable arrangement has been found

03:20

and copied to the other foundation positions within the bridge model.

03:25

Using this process,

03:26

the bridge designer can rapidly develop a conceptual bridge

03:29

design containing the general direction of the project.

03:32

With the initial thoughts constraints

03:34

to a more crystallized state that can

03:36

be developed further as the project progresses.
