Project 1

ABSTRACT:
The aim of the project is to design a multi storied building of G+ 5 floors, at kalakode about 4
km from paravoor. The design is done by taking in to account the requirements and standards
recommended by IS code, Kerala building rules and national building rules.
Planning is done using the 3D modeling software Revit 2011 with the help of Auto CAD 2014.
The structure analysis and design is done using STAAD.PRO.V8i and a cross check is done for
selected members using limit state method of design as per IS 456-2000. STAAD. Pro uses a
command language based input format, which can be created through an editor called the editor
file, the powerful STAAD.Pro graphics input generator or through CAD based input generators
like AutoCAD. Output generated by staad.pro consists of detailed numerical results for analysis
and design.
Key word: multistoried, planning, analysis and design, staad.pro.
1.INTRODUCTION
Buildings are an important indicator of
social progress of the country. A building
frame is a three dimensional structure or
space structure consist of column, beams
and slabs. Nowadays, high rise buildings are
in high demand due to the world population
boom. Earlier, modeling and structural
analysis of buildings were carried out using
hand calculation method based on simplified
assumptions and understanding the whole
behavior of the structure .But it seems to be
time consuming and complicated for high
rise buildings .At present ,computer
hardware’s and software’s for modeling and
analysis of structure is widely available. We
need to know how the knowledge secured in
the class room are applied in these practical
side of work. When we got this project, we
come into practical field to collect
construction techniques and to meet the
various difficulties in the construction. Also
it is necessary to have sufficient knowledge
regarding the various softwares currently
used in planning analysis and design of
structure

2. LITERATURE SURVEY
High rise buildings are in high demand
because of the world population boom and
development of technology during past
decades. Various structural forms and
construction materials were developed along
with a diverse assemblage of structural and
non structural components .the real
performance of the high rise structures
depends greatly on the integrated interaction
of structure and non structural components.
This makes the behavior of high rise
structures complicated.
In current design practice, the
lateral load resisting system of a high rise
building is considered vital to the whole
structure. It is commonly recognized by
engineers that the load resisting system of a
multi storied building is a system including
mainly structural components such as
columns, beams, and shear walls. In facts
through, non structural components also
contribute to the lateral performance of high
rise building. Observable gaps exist between
the real performance of buildings and the
behavior predicted by design theory. in
practice, buildings performs as an integrated
system of structural and non structural
components but the nonstructural
components are considered non load bearing
and are not included during the design
process of the primary structure. Since the
1990s specialist software has become
available to aid in the design of structure
with the functionality to assist the drawing ,
analyzing and designing of structures with
maximum precisions, example includes
AutoCAD, Staad.Pro, ETABS, Prokon, revit
structure, etc. such soft ware may also take
into consideration environmental loads such
as from earth quakes and wind.

4. ANALYSIS AND DESIGN OF
BUILDING
Step - 1 : Creation of nodal points.
Based on the column positioning of plan we
entered the node points into the STAAD file
Step - 2: Representation of beams and
columns.
By using add beam command we had drawn
the beams and columns between the
corresponding node points.
Step - 3: 3D view of structure.

Here we have used the Transitional repeat
command in Y direction to get the 3D view
of structure.
Step - 4: Supports and property assigning.
After the creation of structure the supports at
the base of structure are specified as fixed.
Also the
Materials were specified and cross section of
beams and columns members was assigned.
Step - 5: 3D rendering view.
After assigning the property the 3d
rendering view of the structure can be
shown
Step - 6: Assigning of seismic loads.
In order to assign Seismic loads firstly we
have defined the seismic loads according to
the code IS1893:2002 with proper floor
weights. Loads are added in load case details
in +X,-X, +Z,-Z directions with specified
seismic factor.
Step - 7: Assigning of wind loads.
Wind loads are defined as per IS 875 PART
3 based on intensity calculated and exposure
factor. Then loads are added in load case
details in +X,-X, +Z,-Z directions.
Step - 8: Assigning of dead loads.
Dead loads are calculated as per IS 875
PART 1 for external walls, internal walls,
parapet wall
Including self-weight of structure.
Step - 9: Assigning of live loads.
Live loads are assigned for every floor as
3KN/m2 based on IS 875 PART 2.
Step - 10: Adding of load combinations.
After assigning all the loads, the load
combinations are given with suitable factor
of safety as per IS 875 PART 5.
Step - 11: Analysis.
After the completion of all the above steps
we have performed the analysis and checked
for errors.
Step - 12: Design.
Finally concrete design is performed as per
IS 456: 2000 by defining suitable design
commands for different structural
components. After the assigning of
commands again we performed analysis for
any errors.

and viewing of structural models both 2D
and 3D situations. All other specifications
like section properties, material constants,
support load, analysis and design
requirements, printing, plotting facilities are
available. A versatile “query” facility allows
generation of customized reports. Powerful
icons based graphics tools provide
