Modeling Templates
- Selection of templates for quickly starting a new model
- Edit spacing, story dimensions and Units
Section Properties
- Concrete Sections
- Easy to define standard concrete shapes and rebar layouts
- Steel Sections
- Easy to define standard steel shapes
- I/Wide Flange Channel
- Double Channel
- Tee Angle
- Double Angle
- Pipe
- Tube
- Steel Joist
- Built up steel sections
- Easy to define standard steel shapes
Section Designer
- Specialized sections
- Allows users to create any arbitrary shape and any user defined material
- Automatically calculates all section properties
- Generates biaxial interaction diagram for concrete sections
- Moment curvature diagrams
Frame Elements
- The frame elements in ETABS are defined as beams, columns or braces.
- Intermediate joints will automatically be generated where other members intersect with frame to ensure finite element connectivity.
Shell Elements
- The Shell Element in ETABS are defined as slabs, walls or deck properties
- Use the Wall/Slab Section to define the parameters for the wall or slab section
- Deck Section properties can be defined as filled or unfilled deck and solid slab
- Area Shell Types:
- Shell
- Plate
- Membrane
Shear Walls
- Draw complex 2D and 3D shear walls
- Walls can interact with beams and columns
Piers and Spandrels
- Pier and spandrel labels produce integrated shears and moments for design purposes, for walls modeled with area finite elements.
- For example, an assemblege of 20X20 meshed shear wall areas could have results displayed and reported as if it were a single column.
Windows and Doors
- Draw command for windows and door openings in walls
- Automatically meshes wall around door/window openings
Link Properties
- ETABS has a many different link elements available for users to accurately represent the behavior of a structure.
- Linear
- Gaps
- Hooks
- Dampers
- Friction
- Isolators
- Rubber Isolators
Hinge Properties
- Force-deformation relations for steel and concrete hinges
- Frame hinges for axial, flexural, shear and torsional behavior
- Capacity spectrum conversions effective damping calculation
- Summary reports including plastic hinge deformations
Meshing Tools
- ETABS automatically meshes area objects that are assigned deck properties or slab properties
- Meshing helps distribute loads realistically
- User has full control of how mesh gets generated
- Reshaper tool can be used to reshape and control mesh geometry
Automatic Line Constraint
- Automatic Line Constraint technology for mismatched meshes.
- Line Constraints automatically appear at the lines where the floor and wall objects intersect.
- Displacement compatibility enforced when mesh geometries do not match.
Extrusion Tools
- Linear or radial extrusion available for points and lines
- Generate a cylindrical surface from radial extrusion of a single line
- A two-dimensional object, area or shell, can be generated from a one-dimensional object, the line object
Rigid, Semi-Rigid and Flexible Floor Diaphragm
- Apply diaphragm constraints to all corner points of area object
- Diaphragms can be assigned to joints objects
Developed Elevations
- Elevations along gridlines
- Developed elevations along strips
- Editing and assignments in elevation view
