3. ABSTRACT
Schools are very challenging to plan, they are important for preparing the
future human resource and directly contribute to social and economic
development of a place. This ppt presents an innovative analysis and design
approach for a school building. The analysis and design of building, is very
important for a structural engineer to save time. Analysis and design of a
Multistoried school building by using a software ETABS. For analyzing a
multi storied building one has to consider all the possible loadings and the
structure is safe against all possible loading conditions. There are several
methods for analysis of different frames like Kani's method, cantilever
method, portal method, Matrix method. The present project deals with the
analysis of a multi storied school building of G+3.
4. By referring to various research papers it is concluded that software based
analysis and design is accurate and also it can save as compared to manual.
So, Hence this proposed major project work ETABS (Extended three
dimensional analysis of building system) software is being selected for
analysis and design.

INTRODUCTION
6. There are mainly 5 essential steps to be followed for the design of any
structure. (1) modelling, (2) load analysis, (3) structural analysis, (4)
structural design and (5) detailing.
Analysis
• Finding out internal forces (axial force, shear force, bending
moment), stress, strain, deflection etc in a structure under
applied load conditions.
Design
• Establishes the overall concept for the structure, helps to check that the
structure is safe, specification in the form of a prototype.
Framed R.C.C structure
Materials used:
53 grade (used for R.C.C works)
Concrete: M30 grade for R.C.C
Steel: HYSD TMT rods (Fe500)
7. LITERATURE REWIEW
B. Gireesh: Studied the structural and seismic analysis of G+7 structure
using the Stadd.Pro software. In this study the design was based on the
following Indian standard codes: IS 1893 (Part 1) – 2007, for the design of
base shear. After starting the project various dead load, live load, wind
load, snow load and wind load was imposed for which the analysis will
run.
Aman et.al : The analysis and design of C+G+5 residential cum
commercial building based on the criteria defined by the IS codes on
Stadd.Pro software. The load imposed were only dead and live load hence
the load combination generated was 1.5(D.L. + L.L.) after which the
analysis of the building was done for the Frame and the resulting Bending
moments and shear forces were studied.
8. Mahesh et.al : This study was focused on the analysis of the structure in
the effect of wind load on the by the software Stadd.Pro. The design of wind
was based on the Indian standard code IS 875.
V. Varalakshmi : The design and analysis of multistoried G+5 building at
Kukatpally, Hyderabad, India. The study includes design and analysis of
columns, beams, footings and slabs by using well known civil engineering
software named as STAAD.Pro.

METHODOLOGY
11. Loads
• Dead loads: means the self-weight of the structure
• Live loads: occupancy of people in buildings, moving equipment, and the
movement of cars on bridges;
• Wind loads: any horizontal, uplift or shear pressures or forces that the wind exerts
on a building;
• Snow loads: only applicable for structures expected to receive snowfall;
13. Limit state of design:
• Limit state method of design in a factor improvement of ultimate load design. In the
limit state method, a structure is going to design withstand all loads likely to act on
in the duration of its life span also to satisfy the serviceability requirements like
deflection, limitation and crack width.
14. Design of members:
Design of slabs.
Design of beam.
Design of columns.
Design of footing.
Slabs
A molded layer of plain or reinforced concrete, usually of uniform but sometimes of
variable thickness.
One-way slab: The ratio of the longer side, L, to the shorter side, S, is 2 or more, L/S
≥ 2.0, then, the slab will act as a one-way slab
Two-way slab: The ratio of the longer side, L, to the shorter side, S, is 2 or more,
L/S< 2.0, then, the slab will act as a two-way slab
15. Beams
Structural member that carries a load that is applied transverse to its length.
Singly reinforced beams
The beam that is longitudinally reinforced only in tension zone, it is known as
singly reinforced beam.
Doubly reinforced beams
Reinforced concrete beam with steel reinforcement both in tension and
compression zone is called a doubly reinforced beam.
Columns
Structural element that transmits, through compression, the weight of the
structure above to other structural elements below.
Axially loaded column
Load is acting exactly at the centroid of column is called axially
loaded column.
16. Uniaxial eccentrically loaded column
Axial load and bending moment acting along one direction is known as
uniaxial loaded column.
Biaxial eccentrically loaded column
Axial load and bending moment acting along both directions is known as
biaxial loaded column.
Footings
The bottom part of a foundation is called the footing. Footings in construction
are critical, as the footing distributes the weight of the building evenly across
the entire structure
Shallow foundation
Depth of the foundation is less than or equal to width of footing is called as
shallow foundation
17. Deep foundation
Depth of the foundation is greater than width of footing is called as
deep foundation.
18. IS Codes for Design
IS 456: 2000 – Plain and Reinforced Concrete
IS 875 (Part 1-5): 1987 – Code of practice for design loads (Except earthquake
load) for buildings and structures
Part 1: Dead loads
Part 2: Imposed (live) loads
Part 3: Wind loads
Part 4: Snow loads
Part 5: Special loads and load combinations
SP 16: 1980 – Design Aids (for Reinforced Concrete)
IS 456: 1978 SP 24: 1983 – Explanatory handbook
IS 456: 1978 SP 34: 1987 – Concrete Reinforced and Detailing
19. RESULTS
The shear force and bending moment diagram for the framed structure for school building
by using ETABS software. Shear force refers to the internal forces that act parallel to the
cross section of a structural element. In buildings, shear forces primarily arise from the
vertical loads acting on the structure. For example, the weight of floors, walls, and roofs, as
well as the live loads, contribute to shear forces in beams and columns.
A bending moment is a measure of the bending effect or internal forces within a structural
20. element due to external loads. In buildings, these external loads typically include the
weight of the building materials, occupants, furniture, and other live loads such as
snow or wind. Bending moments cause structural elements, such as beams and
columns, to experience tension and compression.
Model has been checked

22. CONCLUSION
The Multi-storey school building is analysed and design. All the results of
analysis and design are safe. The limit state method of design is used for
design of all the compenents. In this project we are done analysis and design a
school building as framed structure. The shear force and bending moment

software. Analysis and design of Multi-Storey School building having G+3
storeys is done. Analysis is done by using the software ETABS, which proved
to be premium of great potential in analysis and design of various sections.
