ETABS – Base Unit and Design Standards

4 min read

Step 1: ETABS – Base units and Design Standards.

To open ETABS click on the appropriate desktop shortcut or by selecting ETABS from Windows start menu. This will open the ETABS main window. Then from the pop-up a user select units and design code.

New Model

To create a new model, Select ‘new model’ in the file menu. To determines the default definition be used, it will open model template settings for initialization of units, default section database, and design code.

As you click on New model, you can see that the Pop up gives three options

Model initialization etabs DESIGN
Model initialization ETABS
  1. Use saved user default setting
    This option includes the display units, preferences, properties and definitions.
    For the first time use, saved user settings will be unavailable.
  2. Use settings from a model file
    Selected this option, User can import the display units, properties, definitions and preferences from a saved file.
    This option does not import Objects and assignments from the file.
    When a client demands work in different units, this option comes in handy.
  3. Use built-in settings with.
    This option requests the user to specify display unit, steal session database, code for design of steel and concrete member.
    The user can change it and use it according to his need.
    Indian user can start with standard MKS or SI units, selecting Indian code for steel section,  choosing IS 800:2007for steel design code, using IS 456:2000 for concrete.

On satisfaction with settings, the user can proceed by clicking on OK.
Clicking OK, a new model window pops ups.
This window is called a New Model Quick Template.

New Model Quick Template

Here a user can change the grid dimensions, the story dimension and the structural object with which user want to start the modeling.

Grids Dimensions

If the user decides to use Uniform spacing in X and Y directions then he can specify the distances in the given Uniform Grid Spacing options.
The user can go for a custom grid if they want to have varying distances between girds lines in X and Y directions.

Story Dimensions

Define the number and height of stories in the model.

1. Simple Story Data

Specify the values of the Number of Stories, Typical story height, bottom Story height.
The value specified in the typical story height will be used for all the other stories except the bottom story.

2. Custom Story Data

Specify the story height, elevation, if the story is a master story or not, if it is Master story then which other story is similar to that Master story.

Add structural objects

Creates a model based on the template.

1. Blank

The program opens display windows but does not load any grid or story dimension data specified by default on the new model quick templates. this option maybe Ideal while importing a model from another program file to start a new model

2. Grid Only

A grid system will be added to the model without any structural objects. Proceed to build the model using the Draw and Edit menu commands to draw the structural objects.

3. Steel Deck

Use the structural geometry and properties for steel deck form to define a steel flow system.

4. Staggered Truss

Use the structural geometry and properties for staggered truss form to define a staggered Truss system.

5. Flat Slab

Use the structural geometry and property for flat slab form to define a concrete flat slabs floor system with drop panels.
No beams are included in the floor system.

6. Flat Slab with Perimeter Beams

Use the structural geometry and properties of a flat slab with parameter beam forms to define a concrete flat slab floor system with drop panels and perimeter beams.

7. Waffle Slab

Use the structural geometry and properties for waffle slab form to define a concrete Waffle slab floor system with drop panels and perimeter beams.

8. Two Way or Ribbed Slab

Use the structural geometry and properties of two way or ribbed slab form to define a one-way ribbed concrete floors Slab system or a conclave flat slab floor system with beams interconnecting all the columns. This template does not include drop panels.
