TEE BEAMS SUPPORTING CONTIUOUS SLAB

Aim:-

To draw the Tee beam supporting continuous slab using AutoCAD software

Problem

The following are the particulars of a continuous one way

slab over Tee beams.

Clear size of room - l5mx5m

Spacing of Tee beams - 3m c/c

Depth of Tee beams - 450 mm (over all)

Breadth of web or rib - 250 mm

Width of support - 250 mm

Thickness of slab - 120mm

Reinforcement in slab

Main reinforcement for positive moment at end

spans 10 mm Fe 415 steel @300 mm c/c.

Main reinforcement for negative moment at support

next to end support 10 mm Fe 415 steel at 290 mm c/c.

Main reinforcement for positive moment at Interior

span 10mm Fe 415 steel @300mm c/c.

Main reinforcement for negative moment at Interior

support 10 mm Fe 415 steel 230 mm c/c.

Distribution 8 mm Fe 415 steel 340 mm c/c.

Reinforcement in Tee Beam

Main (Tensile) reinforcement - 20 mm Fe 415 steel 5 Nos.

Hanger rods - 12 mm Fe 415 steel 2 Nos.

Shear reinforcement - 2 legged stirrups 8mm Fe 415 steel @25OmmcIc.

Reinforcement at top at support 16 mm Fe 415 steel 2 Nos for a length 0.1 l or Ld whichever in greater and

anchored sufficiently.

Anchorage and curtailment of reinforcement may be adopted with standard values and any more data required may be assumed. suitably

Draw the following views to a suitable scale.

1. Lay out of beams

2. Cross section of beam and slab for end span and interior span showing reinforcement details.

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

4. Longitudinal section of Tee beam.

5. Cross section of beam at mid span and at supports.

6. Prepare a bar bending schedule for all spans except beam

portion for 1 m width of slab.

 

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 Tee beam supporting continuous slab are drawn.

7. using hatch command where our necessary

8. Dotted lines are drawn using line type.

Result:

Thus the Tee beam supporting continuous slab are drawn using Auto CAD 2014 software
