SIMPLY SUPPORTED TWO WAY SLAB(CORNERS NOT HELD DOWN)

Aim:-

To draw the Simply supported two way slab( corners not held down) using AutoCAD software

problem: The following are the particulars of a simply supported two way slab ,and in which corners are not held down.

Size of the room – 3.5x7.5m

Thickness of slab - 150mm

Width of supporting walls - 300mm

Thickness of wall=500mm

Clear cover - 15mm

Reinforcement along shorter span(Main bars) Fe 415 steel –12mm @ 150mm c/c

Reinforcement along longer span (Distribution Bars Fe415 steel-10mm @ 200 mm c/c

Distributors at top for the main reinforcement in both

Anchorage and curtailment of reinforcement maybeadopted with standard values and any more datarequired may be assumed suitable.

Draw the following views to a suitable scale

1. Section along shorter span showing reinforcement details

2. Section along span showing reinforcement details

3. Plan showing the reinforcement details at bottom and at top

4. Prepare a bar bending schedule .

Procedure:

1. switch on the computer

2. Open Auto CAD 2014

3. Setting units

( ii) set the unit as decimal & millimeter

4. Setting limits

5. Zoom – All

6. Using Line command Simply supported two way slab( corners not held down) are drawn.

7. using hatch command where our necessary

8. Dotted lines are drawn using line type.

Result:

Thus the Simply supported two way slab( corners not

held down) are drawn using Auto CAD 2014 software
