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.

  • 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.

  • 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.

  • Place 6 x 6 (0.15 m x 0.15 m) wood columns at the grid intersections on the right side of level 2 (along grids C and D) and align edge columns to the outer boundary of the floor slab.
  • Place5 x 22 (0.13 m x 0.57 m) Glulam beams of southern pine along grids C and D to support the floor level above. Use an offset -0.75" (-19 mm) to place these beams below the plywood subfloor at Level 2.
  • Create a beam system of 16" (0.40 m) TJL wood open web joists to span between the beams at grids C and D. Use an offset of -0.75" (-19 mm) to also place these joists below the plywood subfloor. The joists should be center justified and spaced at a fixed distance of 2’ (0.61 m).
  • Create a similar beam system using 14" (0.36 m) TJL wood open web joists to span between the beams at grids B and C.
  • Copy the wood structural elements that you created in this exercise to similar locations on levels 3 and 4.
  • Select the floor at level 4 and change it to the plywood floor type.
