Building Information Modelling

Revit Structure 2015 (BIM)

Revit is a design and documentation platform that supports the design, drawings, and schedules

required for building information modeling (BIM). In the Revit model, every drawing sheet, 2D and 3D view, and schedule is a presentation of information from the same underlying building model database.

The Revit parametric change engine automatically coordinates changes made anywhere—in model views,

drawing sheets, schedules, sections, and plans.


Building Information Modeling Parametric modeling refers to the relationships

among all elements in a project that enable the coordination and change management that Revit provides. These relationships are created either automatically by the software or by you as you work.

Revit uses 3 types of elements in projects: model elements, datum elements, and view-specific elements. Model elements represent the actual 3D geometry of the building. They display in relevant views of the model.


Building Information Modeling Model elements represent the actual 3D geometry of the

building. They display in relevant views of the model.

Examples: Structural walls, slabs, and ramp Datum elements help to define project context. For

example, levels and reference planes are datum elements.

View-specific elements display only in the views in which they are placed. They help to describe or document the model. For example, dimensions are view-specific elements.


Building Information Modeling


Building Information Modeling Each element you place in a drawing is an

instance of a family type. Elements have 2 sets of properties that control their appearance and behavior: type properties and instance properties. For Example: cross-sectional dimensions of a beam are type properties, if you select a beam, and change one of its instance property values on the Properties palette, only that beam is affected.


Building Information Modeling Revit Terminology: Most terms used to identify objects

in Revit are common- Project- Level- Element- Category- Family


Revit Structure 2015 Project: In Revit, the project is the single database

of information for your design—the building information model. The project file contains all information for the building design, from geometry to construction data. This information includes components used to design the model, views of the project, and drawings of the design. (plan views, elevation views, section views, schedules, and so forth)


Revit Structure 2015 Level : Levels are infinite horizontal planes that

act as a reference for level-hosted elements, such as roofs, floors, and ceilings. Most often, you use levels to define a vertical height or story within a building. You create a level for each known story or other needed reference of the building; for example, first floor, top of wall, or bottom of foundation. To place levels, you must be in a section or elevation view.


Revit Structure 2015 Element: When creating a project, you add

parametric building elements to the design. Revit classifies elements by categories, families, and types.


Revit Structure 2015 Category: A category is a group of elements that

you use to model or document a building design. Examples Categories of model elements:

- walls, beams Categories of model elements

- Categories of annotation elements:

tags, text notes


Revit Structure 2015 Family: Families are classes of elements in a

category. A family groups elements with a common set of parameters (properties), identical use, and similar graphical representation. Different elements in a family may have different values for some or all properties, but the set of properties - their names and meaning - is the same.


Revit Structure 2015 Revit uses the following kinds of families: - Loadable families can be loaded into a project

and created from family templates.- System families are not available for loading or

creating as separate files. - Examples Walls, dimensions, ceilings, roofs,

floors, and levels

• Levels: Use the Level tool to define a vertical height or story within a building. You create a level for each known story or other needed reference of the building (for example, first floor, top of wall, or bottom of foundation).

• Grids: Use the Grid tool to place column grid lines in the building design. Grids can be straight lines, arcs or multi-segmented.


Grid


Structural Modeling

Structural Modeling : Add structural elements to the building model.

- Structural Columns :Use the structural column tools to add vertical load-bearing elements to building models.


Beams Beams: Use beams tools to add load-bearing structural

elements to building models.

- Beam Systems: Use beam system tools to add a single structural framing element that contains a series of individual beams placed in parallel to a building model.

Braces: Use brace tools to add diagonal members that are connected to beams and columns.


Beams


Trusses Use the Truss tool to add a truss to your

building model according to the layout and other parameters specified in the selected truss family type.


Opening to a Structural Framing

Add an Opening to a Structural Framing Element

To cut an opening in a structural element

1. On the ribbon, click Opening By Face. Where is it?

2. Select the desired plane of the member to which you want to add an opening.

3. Using the Draw panel sketching tools, sketch the opening on the structural element

4. On the ribbon, click Mode panelFinish Edit Mode


Opening to a Structural Framing


Structural Stiffener to an Opening Add a Structural Stiffener to an Opening

- Use stiffeners to strengthen steel framing members, especially beams and columns in which there are openings.

- Stiffeners are modeled as Revit loadable families that represent the additional steel reinforcing material.


Openings


Structural Walls Create a Shear, Bearing, or Structural combined

structural wall. Wall Foundations Isolated Foundations


Structural Floors Use the structural floor tool to add structural

floors to a building model.
