Drawing/Creating line

sections

To draw beams in plan

select and left click once at the beginning of the line. Drag the mouse to the end location of the line and left click again. Note that as the mouse is dragged a dashed line is visible. It indicates the current extent of the lineobject.

To create beams in plan

select and Click on any grid and a line object is drawn on that grid line between the two adjacent intersecting grid lines from the same coordinate/grid system.

To create columns in plan

select and Left click at any location in a plan view to draw a column (vertical line object below).

Drawing/Creating area

sections

To create slabs in plan

select from draw bar. Left click once at the first corner point of the area; drag the mouse to each corner point of the area object.

Alternatively you can also

use or .

To create walls in plan

select from draw menu Left click once at the first corner point of the area, drag the mouse to each corner point of the area object.

Click this or select load cases command from define menu to define load cases.

Click to add new loads as per data shown in top row

Modify lateral load form modify as specified

Defining load cases

Click to modify the highlighted load as per the data shown at top

Click to modify load

*Self-Weight multiplier to be given unity for dead load only and zero for rest

OR alternatively Etabs provides us to load default set of load

combinations

Click this tab form define menu to specify load cases

Defining load combination

Click to add default Combos.

Use concrete frame designs

Etabs provides a variety of ways to select objects to ease and speed up the user

as per his requirement. Here are some ways select objects:-

Select an object by click on it

Select an object by clicking and dragging your mouse from left to right

around the object forming a rubber band box. It selects the objects fully

inside the box.

Select an object by clicking and dragging your mouse from Right to left

around the object forming a rubber band box. It selects the objects

intersecting the box and the objects fully inside the box.

Select objects

Selection can also be done by intersecting line. It selects objects

intersecting the selecting lines.

Another way of selecting objects is by selecting from select menu

Also selection can be made using the set building view options

and viewing only the desired objects (say beams)

and select the required beams.

Also as defined earlier and are also used to select all and get

perivious selection respectivly.

is used to deselect all.

Hinged support

Fixed support

Getting familiar with

assign menu

* By default ETABS takes support as hinged

For releasing frame releases

For proper allocation of local

axis

For proper allocation of frame

sections

To define area sections

To define diaphragms

To assign local axis to area sections

Used to assign loads to line objects

Used to assign Point loads to

lines

Used to assign distributed

loads to lines

Defining mass source

It is necessary to define mass source to apply earthquake load.

Click to define Mass source

To define Mass from loads

take dead and live loads as a

combo shown or as specified.

Defining frame output stations

Select required line type i.e. beam or column

For beams set as 13 (or as required).

For columns set as 3 (or as required).

More the number of station more accurate the analysis is but it is

more time consuming.

Analysing the model

Set analysis options

Check model for warnings

Run Analysis

Click for concrete design

View shows longitudinal

reinforcement

As our unit was meters and

reinforcement is comparatively

small, it is shown e.g. as

1.56e-04 so it becomes difficult

to read so change to a smaller

units.

Post analysis

Start concrete design/check of

structure

Now value of longitudinal

reinforcement is easily visible

Shear reinforcement

Click display design Info in the drop down

beside

Select shear reinforcement from the

drop down box beside design output

and click OK

Now Etabs shows reinforcement

required by the sections against

shear at ends and in middle.

The values shown here shown are

used to calculate the specification of

shear stirrups to be provided in

accordance to

ASV/SV= shear reinforcement req.

Where ASV is area of stirrup

SV is spacing of stirrups

Before selecting any tables following steps are common for all.
