Steps for Structural Design

OBJECTIVE` OF STRUCURAL DESIGN

Structure design should

satisfy the criteria of ultimate strength.

Structure should satisfy

the serviceability.

It should satisfy the stability

against overturning , sliding , and

buckling.

Information required before starting the structural design

1. A set of Architectural Drawings

2. Soil investigation report

3. Location in order to decide on wind and seismic loadings

ASSUMPTION AND NOTATION ASSUMED

• The notation adopted throughout the work is same as in IS 456-2000

• Partial safety factors for loads is in accordance with clause 36.4 of IS 456-2000

• Partial safety factor for material in accordance with clause 36.4.2 IS 456-2000 is taken as 1.5 for concrete and 1.15 for steel.

Design Step

Step 1: Elementary survey

Location & Zone

Dimension of plot

Soil properties

Study the plan for slab, beam,

column.

Select suitable

dimensions for structural

elements

If need any improvement in

architectural drawing then discuss with

architect.

Step 2: Architectural drawings.

Step 3:Design of Slabs.

The slabs are designed as one-way or two-way panels, taking the edge conditions of the supporting edges into account.

The design of floor slab is

carried out as per clause 24.4 &

37.1.2 & Annexure D of IS:

456-2000

Control of Deflection can be checked as per clause 23.2.1, 24.1 & Fig 4. of the IS:456-2000

Step 4: Design of Beams.

The beams are designed as continuous beams, monolithic with reinforced concrete columns with their far ends assumed fixed.

The whole process of designing the beam is as per Clause 23 of IS:456

Step 5: Design of columns.

• Columns are designed as per Clause 25 of IS 456:2000

• Column should be designed as axial member.

Step 6: Create engineering drawings.

Create and generate the foundation plan.

Create and generate the roof plan.

We have to show only structural components of the building – columns, beams and slabs.

Step 7: Final check and submission.

Check all design calculations and drawings.

Remember to put your name and your partners names on all documents and drawings.

Notes can be rough – they do not need to be typed – but please make sure that all of your notes are neat and legible.
