This document describes the design and analysis of a 15-story residential building. It includes details on loads, materials, and the structural design of key components like slabs, beams, columns, footings, and a water tank. Loads considered include dead loads from structural elements and imposed live loads. Manual analysis is performed using the Kani's method to check the frames. The objectives are to satisfy strength, serviceability, stability, and design the foundation, columns, beams, slab, and water tank. Reinforcement is checked for development length and shear capacity.

3. INTRODUCTION
 Our project is based on the design and analysis
of the multi-storied building.
 Live loads and dead loads are taken into
consideration and analysis is done manually.
 Notation adopted through out the project is
same as in IS-456-2000.

4. STATEMENT OF THE PROJECT :

5. 1.Utility of building : Residential building
2.Shape of the building: Rectangular
3.Type of walls : Brick wall
4. No . of flats for each floor : G+14

6. Geometric details :
Floor Height : 3.0 M
Height of Plinth : 0.6 M above G.L
Depth of Foundation : 6 ft below G.L

7. Material details :
 Concrete Grade : M15, M20
 Grade of steel : HYSD
 REINFORCEMENT of Grade Fe415
 Bearing Capacity of Soil : 400 KN/M2
 Type Of Construction : R.C.C
 framed structure

8. DIFFERENT TYPES OF LOADS ON
STRUCTURE
 Dead loads
 Imposed loads
 Wind loads

9. Dead loads
Involves self weight of
RCC slab
Beams & columns
Plinth
Walls

10. Imposed loads
 Imposed also known live loads
 Load over the floor i.e. load of persons it
is calculated as 0.5 kN/m2
 This load is applied over the length
of structure

11. Wind loads
 Wind is air in motion
 Intensity of wind and exposure are
applied
in the directions as required

12. TYPES OF LOADS IMAGE VIEW

13. 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
 DD + LL = 1.5
 DD + LL + WL = 1.2

14. Density of materials used
MATERIAL DENSITY
i) Plain concrete 24.0 KN/m3
ii) Reinforced 25.0 KN/m3
iii) Flooring material 20.0KN/m3
iv) Brick masonry 19.0KN/m3

15. OBJECTIVES OF STRUCURAL DEIGN
 Structure designed should satisfy the
criteration of ultimate strength.
 Structure should satisfy the serviceability
 It should satisfy the stability against
overturning , sliding , and buckling.

16. The main objective of the design
are
 Foundation design
 Column design
 Beam design
 Slab design

17. Structural design
 For slabs , Depth is 120 mm provided
 Factored Load on slab is 9KN/m
 For beams, after calculations are done. the
Dimensions of beam is 230*420mm

18.  Shape of column is Rectangular
 For columns, the dimension of column is
230*350mm & 230*450mm
 For footings, the bearing capacity of soil is
400Kn/m2
 To provide the dimension of footing is
2000*2000mm

19. DESIGN OF THE SLAB
 If Lx/Ly < 2 two way slab.
> 2 one way slab.
 LOADS ON SLABS :
 Dead load = thickness * unit weight of
concrete.
 Live Load for slab = 2.5
 CALCULATION OF B.M:
M x = α x W Lx
2
M y = α y W LY
2
 Check for depth d = √ ( Mu/2.7*b)

20.  REINFORCEMENT :
Mu = 0.87 f y A s t d [1- Ast*fy/bd*fck]
• Max Dia of the bars = 10mm
• Spacing of the bars 300 mm c/c
• CHECK FOR DEVELOPMENT LENGTH :-
Id = (Øσs)/(4Ʈbd)
• CHECK FOR SHEAR
Vu / b d

21. DESIGN OF BEAMS
 Max Dimensions of the beam
230*420mm
230*520mm
 Max Dia of the beam = 12mm HYSD
bars.
 Clear cover of the beams = 25mm.

22. DESIGN OF COLUMNS
• Max dimensions of the columns
230*350mm
230*450mm
• Max diameter of the bar = 16mm
• Clear cover = 40mm

23. FOOTINGS

24. STAIR CASE
 Type : Open – newel stair case
 No. of flights = 3
 No. of steps for flight = 7

26. ANALYSIS
 Analysis of frames is done by using KANIS
Method.
 The KANIS Method to be simple for multi
storeyed building.
 Analysis is done for RCC structure
 M ab=MF ab +2M’ab +M ’ba
 M ba=MF ba +2M’ba +M’ ab

31. DESIGN OF WATER TANK
 Capacity required 32000 lit
 wall thickness 200 mm
 Area of the tank 2.6 x 3.6 m2
 Total Height of the water tank 3.96 m
 Total load 4 KN/M2
 Reinforcement provided 8 mm Ø bars at
240 mm c/c

32. RCC analysis
 Code is assigned as IS:456-2000
 The parameters are assigned to the structure
 Commands to be given are
concrete design

33. Conclusions
 It is Manual design.
 we can do this analysis within no time but
the basic thing is to know the concept
behind it.
 The same result can be achieved using
the software like “Staad-Pro”.
