STRUCTURAL DESIGN

• Design of Slabs
• Design of Beams
• Design of Girders
• Structural Analysis using Staad system
• Structural Design of Columns
• Design of Footings
• Design Drawings by using Auto-Cad

12
DIFFERENT TYPES OF LOADS ON THE STRUCTURE

• Dead loads
• Imposed loads
• Wind loads
• Seismic loads

13
DEAD LOADS

• Involves self weight of
• Rcc slab
• Beams columns
• Plinth
• Walls

14
IMPOSED LOADS

• Imposed also known live loads
• Load over the floor i.e. load of persons it is
  calculated as 0.2 kn/m2
• This load is applied over the length
• of structure

15
WIND LOADS

• Wind is air in motion
• Wind loads are calculated according to
• IS875 (part 3)
• Intensity of wind and exposure are applied in the
  directions as required

16
TYPES OF LOADS IMAGE VIEW
17
LOAD COMBINATIONS

• The structure should be analysed for
• combination of loads as in practice
• we have number of loads in various directions act
• Some of the combinations to be
• checked are
• a. 1.5(DLLL)
• b. 1.5(DLWL)

18
OBJECTIVES OF STRUCTURAL
DESIGN

• Structure designed should satisfy the ultimate
  strength.
• Structure should satisfy the serviceability
• It should satisfy the stability against
• overturning , sliding , and buckling.

19
THE MAIN OBJECT OF THE DESIGN

• Design of Slabs
• Design of Beams
• Design of Girders
• Structural Design of Columns
• Design of Footings

DESIGN PRINCIPLE,ASSUMPTION AND NOTATION ASSUMED

• The notation adopted thought out the work is same
  as in IS 456-2000
• ASSUMPTION IN DESIGN-
• Using partial safety factors for loads 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
• Using partial safety factors in accordance with
  clause
• 36.4 of IS 456-2000 combination of load
• (D.L L.L) 1.5
• (D.L L.L W.L) 1.2

ANALYSIS

• Analysis is done using STAAD PRO
• developed by BENTLEY
• Once the loads and load combinations are assigned
  to the structure, analysis is to be done
• Analysis is done for RCC structure

RCC ANALYSIS

• Code is assigned as IS456-2000
• The parameters are assigned to the structure
• Commands to be given are
• a.Concrete design
• b.Member takeoff

CONCLUSIONS

• Staad pro become more and more critical in the
  analysis of engineering scientific problems
• This facilities for the implementations of more
  effective professional engineering software
• It should be affordable to promote their wide
  spread usage amongst civil engineering at a
  global scale
