Revit Structure 2013 – New Features

In this post I am going to concentrate on the new features that are specific / beneficial to Revit Structure users.

Reinforcement – Snapping to Fillets and Hooks

Rebar

Structural Wire Fabric

Structural Fabric Reinforcement can be hosted in Structural Floors, Foundation Slabs and Structural Walls. A Structural Fabric Reinforcement element is made up of 2 element types, Fabric Wire and Fabric Sheets.

Fabric Wire is used to define the reinforcing wire, which is used to create the Fabric Sheets. Both of these elements are system families. The templates will be populated with Wires and Sheets that are common in the locality of the template.

Structural Units

Several new unit types have been created:

Reinforcement Area, displayed in:

  • Square feet (SF, ft2)
  • Square Inches (in2)
  • Square millimeters (mm2)
  • Square centimeters (cm2)
  • Square meters (m2)

Reinforcement Area per Unit Length, displayed in:

  • Square Feet per foot (ft2/ft)
  • Square inches per foot (in2/ft)
  • Square millimeters per meter (mm2/m)
  • Square centimeters per meter (cm2/m)
  • Square meters per meter (m2/m)

Reinforcement Spacing, displayed in:

  • Decimal feet (’ , LF)
  • Feet and fractional inches (X’ XX”)
  • Decimal inches (“)
  • Fractional inches (“)
  • Meters (m)
  • Centimeters (cm)
  • Millimeters (mm)
  • Meters and centimeters(m cm)

Reinforcement Cover, displayed in:

  • Decimal feet (’ , LF)
  • Feet and fractional inches (X’ XX”)
  • Decimal inches (“)
  • Fractional inches (“)
  • Meters (m)
  • Centimeters (cm)
  • Millimeters (mm)

Bar Diameter, displayed in:

  • Decimal feet (’ , LF)
  • Feet and fractional inches (X’ XX”)
  • Decimal inches (“)
  • Fractional inches (“)
  • Meters (m)
  • Centimeters (cm)
  • Millimeters (mm)

Crack Width, displayed in:

  • Decimal feet (’ , LF)
  • Feet and fractional inches (X’ XX”)
  • Decimal inches (“)
  • Fractional inches (“)
  • Meters (m)
  • Centimeters (cm)
  • Millimeters (mm)

Additional units:

  • Mass per Area (ex. kg/m2)
  • Mass per Volume (ex. kg/m3)

A number of new unit types have also been added to support other Structural features.

General Structural: Weight, Mass, Displacement/Deflection, Rotation, Period, Frequency, Pulsation, Velocity, Acceleration, Energy

Section Properties: Section Dimension, Section Property, Section Area, Section Modulus, Moment of Inertia, Warping Constant, Mass per Unit Length, Weight per Unit Length and Surface Area

Analytical Model Enhancements

New Analytical Links (formerly known as a Rigid Link)

  • The previous (R2012 and earlier) Rigid link has been replaced with a new Analytical Link Element. In all places where automatic Rigid Links would previously have been generated, now new Analytical Link elements will be generated. These may be selected, deleted and will be restored (if previously deleted) by clicking “restore links” on the analytical adjust toolbar.
  • Analytical Links can now be created manually in places where you need them. In Analytical Adjust mode (Analyze>Analytical Adjust), select Analytical Link. The placement editor will allow you to select 2 nodes between which a new analytical link will be created.
  • Analytical Links have types which allow the user to configure link release conditions.

Physical Material Asset reporting in Analytical Model

Analytical Material

  • The name of the physical asset assigned to the selected physical beam material will be reported in the analytical model properties for quick verification of proper physical material properties.
  • In the Beam (Structural Framing) element the material parameter has been renamed “Structural Material”. Selecting the ellipsis button next to the material name will take you to the materials dialog where you may edit the physical asset of the current beam material or assign a different material.
  • In layered elements e.g., floors, walls the user may elect the material assigned to one of the layers to represent the structural material for the layered element. In the “edit structure” dialog, you will find a new column labeled “structural material”. Check the row which will represent the structural material (to be used for analysis) for this layered element.

Analytical Element and Analytical Node Identification

Analytical elements and analytical nodes now offer Comments and numbering parameters that may be used for identifying these elements in analysis results.
