Load Settings

00:01

SIMON DICKINSON: Hello, my name is Simon Dickinson.

00:05

Let's now look at how we create additional loads in Revit.

00:09

In this video, we will look at creating new loads.

00:13

Creating a load combination sets in a combination formula

00:17

and the usage.

00:21

Let's now look at creating new loads.

00:24

Sometimes we may have to customize the default load

00:28

settings, as each project may have a different requirement.

00:32

We may want to have more than one type of livelihood,

00:36

for instance, people, traffic, furniture, et cetera.

00:40

Load settings in Revit are accessed

00:42

from the structural settings dialog

00:44

box on either the diagonal arrow on the structural panel

00:49

in the structural tab or the structural settings icon

00:52

from the manage tab of a ribbon.

00:55

Here, we can see the load settings that are already

00:58

set up in our template.

01:00

To add a new load, either click at or select a current mode

01:05

and choose duplicate.

01:07

Give it a name.

01:08

In this case, LL2 live load two and assign its nature

01:13

and category, in this case, live and live load.

01:18

Additional natures can also be added if required.

01:22

New case is now ready for use and will be exported to robot

01:26

if used in the model.

01:29

Let's now look at load combinations.

01:32

By default, we do not have any load combinations.

01:36

It is up to us to create these should we require them.

01:41

To create a load combination click Add, and give it to name.

01:45

I'm going to create an imposed combination.

01:49

I will set the type to envelope as I

01:52

want the model to calculate the minimum, maximum result,

01:57

I will specify the state as ultimate

01:60

this will calculate the total capacity of the structure

02:03

to safely resist extreme or factored loads without failing.

02:11

We now need to add a formula.

02:13

Basically, this is the loads we want to combine

02:16

and the factor our coefficient we wish to use.

02:21

To create a new formula, we click

02:23

Add to add each of the loads we required.

02:26

In this case, dead load one live load one,

02:30

and my new live load two.

02:33

As we add a factor value, the formula

02:36

is built and displayed next to our combination name.

02:45

Finally, we can add a usage.

02:49

This is usually defined to either gravity,

02:52

vertical loading, such as the structure, lateral loading,

02:57

such as wind or seismic, or combination a mixture

03:02

of gravity and lateral.

03:05

Once we have added our additional load

03:07

cases/combinations, it is always a good idea

03:10

to check that we can apply these in the project.

03:14

Any geometry we create can be deleted afterwards

03:17

if only used for testing purposes,

03:19

allowing us to save a clean template.
