# Modeling Structural Elements

BIM for Architecture, Engineering, and Construction Curriculum

# Exercise 4.2.1: Linking an Architectural Model and Copying Shared Elements

 In this exercise, students will learn how to: Link an architectural model to a Revit Structure host project. Set the options for copying shared elements. Select and filter the objects to be copied. Create working views of the structural model that facilitates modeling. Figure 4.2.1 - Copying shared elements from a linked model

## Student Exercise

Revit
• Open the model for this exercise in Revit Structure software and link to the architectural model of the building.
• Copy the north-south grids from the linked model into the Revit Structure host project.
• Also create a new 3D view and name it 3D Structural Frame.

# Exercise 4.2.2: Modeling Concrete Columns, Beams, and Floor Slabs

 In this exercise, students will learn how to: Adjust the grids and column locations to better serve the interior layout and structural integrity of building. Specify  and placing concrete columns and beams in plan views and with 3D snapping. Specify the structure and materials for concrete floor slabs. Figure 4.2.3 - Moving columns by adjusting the grid locations

## Student Exercise

Revit
• Place 10" (0.25 m) square concrete structural columns at interior grid intersections on level 1 and the lower level.
• Create a new concrete structural framing type for 12" x 24" (0.30 m x 0.61 m) concrete beams and place these beams at the top of the structural columns on level 1 to support the level 2 floor slab.
• Unhide the floor slab at level 2 and change its type to be a 6" (0.15 m) concrete slab.

# Exercise 4.2.3: Modeling Wood Columns, Beams, and Floors

 In this exercise, students will learn how to: Choose, place, and align wood columns relative to other model elements. Specify the wood beam types and place them in plan views and with 3D snapping. Create beam systems of regularly spaced beams and joists. Specify the structure and materials for wood structural floors and place identical instances at many levels at once.
