In this tutorial, you'll create a simple structural plan using the structural modeling tools available in Revitstructure. For general information on working with Revit and to get started with Revit Architecture, pleaserefer to Getting Started with Revit Architecture.

In this first exercise you create and name a project in which you will create the concrete structure.

Click the application Button. Choose New, then click project

Under template file, make sure the default metric, DefaultMetric.Rte is selected from the RST 2011folder.Make sure Create New project is selected.Click OK

Youll now have a standard project with standard views and an extra 3d view with analytical properties. Ifyou double click on the 3d view 'View 1 – analytical' you won't see anything yet, but this will be the view thatgives you analytical information regarding your project.

Horizontal Grid lines for this project

Adding grid lines

In this exercise, we place a few extra grid lines next to the onesalready in the project.

Go into the plan view 'Level 1'In the Ribbon, on the Home Tab, click grid.Create 5 grid lines with 2 meter spacing. See the exampleat the right. A grid is used as a basis for your entireproject. Grid lines are really planes that run perpendicularto your view. They only visible in views that areperpendicular to the grid planes.

Now repeat this process for the vertical grid lines. When youcreate the first vertical grid lines, it will be numbered as well (number 6). It is customary to use letters forthe vertical grid lines:

To rename the first vertical grid line, double click on the circle tag around the number of the grid line.Change 6 into A, renaming this grid line.Now create the other grid lines. Revit will automatically continue the new naming scheme, namingthem B, C and so forth.

Adding levels

To add levels, you will do the same as you learned in the Revit Architecture tutorial. Create 2 extra levels inthe North view by adding level 3 & level 4 each of which is 3 meters higher than the previous level.

When you've set up you project with a grid and levels, you can start to create your structural model.

Adding Structural Columns

In this exercise you load existing column types from the Revit structure library change the dimensions andcreate custom column sizes. You then place the columns at specific grid intersections.

In the project browser, double-click level 1In the home ribbon tab click the pull-down for Column and select Structural column.Now for the type of column select the Concrete-Regular-Column of 300 x 450mmPlace this column on A1. Making sure that the grid lines are purple when placing. This makes sure thecolumn is in the center of the two grid lines.

Create a new column size

Select the column we created earlier.

Columns on the Grid

Sketch of our Beam System

Click Edit TypeIn the type properties dialog, click Duplicate. Rename to'400 x 400mm'Under dimensions enter 400 for b and 400 for h. Both arein millimeters.Click OK.

Place the new column

This new column will be selected when going back to theplan view.Place this column at each of the gird locations shown atthe right (above)

Making sure the columns have the proper height

Go to your 3d view and select all structural columns.In the properties panel, set the top level to level 4.Click apply.

Creating a Beam System

In this exercise, you'll frame level 1 by adding horizontal beams

Adding beams to level 1:

In the Home tab, click the Beam System buttonDraw a Beam System. Use the example at the right.Click accept to have Revit generate the Beam System.

Notice that Revit creates a certain amount of evenly spacedbeams beams. To change the number of beams (and spacing),change the value for Fixed Spacing in the properties panel:

Using the same beam system for every floor: To maintain the same beam system for every floor we couldcopy paste the floor. However if we ever wanted to change the floor we would have to change all floorsagain. Well be making groups instead, which is more efficient.

Select the beam system.

Beam System Layout of our project

Example of the slabs added to our project

In the Modify Tab, Create Panel, click (Create Group).

Now you can copy this group to other places. Whenever you change something within the group, all otherinstances of the group change as well. Quite handy when making multistory buildings.

Name the group 'Framing'.Tick the 'open in group editor' box and click OK.You are now in the group editor box. This is your 'playground' when editing groups. Exit the groupeditor by clicking the finish button in the top left corner.Go to the North elevation view. Copy the framing group to the 2nd, 3rd and 4th level.

When you go to the 3D View, you can check your structuralframing in 3D. It should be a sound structural system, howeverit still needs framing on the sides to support our beam system.To accomplish this:

Select the beam system group.

In the Modify Tab, Group Panel, click (Edit Group).

Now add a beam, which can be clicked under Structure.Use the example at the rightClick the finish button and voila: the entire building haschanged.

In this exercise, you add concrete slabs to the project.

Open your group editor for the floors.On the Home tab, click SlabNow make a floor for your building, keeping in mind youwill have to atleast cover the framing.Now because the slab lies on TOP of the framing we willhave to give the slab an offset of 200 mmClick the slab and go into the properties window: 'heightoffset from level' should be 200mm.After that click finish once again.

However there is one problem with our slabs, illustrated by the

Beam System fits Slabs after modification

following image:

The current Beam System doesn't support the entire area of our slabs. The next task will be to make thebeam system fit the floor.

Making the Beam System fit the Slabs

In this exercise we will make our beam system fit our structural floor.

Go into the group editor of the Framing group once again.If you cannot see your beam system, rotate until it comesinto view.Select the beam system.Click edit boundary.To make the beam system the same as the floor, delete alllines corresponding to the beam systemClick the (pick lines) drawing tool.

Click all the lines of the perimeter of your floor.
