Objectives
The Objectives of the Project are: Carrying out a complete analysis and design of the main
structural elements of a multi-storey building including slabs,
columns, shear walls.
 Getting familiar with structural soft wares ( Staad Pro
,AutoCAD)
 Getting real life experience with engineering practices

Types of buildings
Buildings
are be divided into:
◦ Apartment building
Apartment buildings are multi-story buildings where three or more
residences are contained within one structure.
◦ Office building
The primary purpose of an office building is to provide a
workplace and working environment for administrative workers.

wind load
The amount of wind load is dependent on the
following:
• Geographical location,
• The height of structure,
• Type of surrounding physical environment,
• The shape of structure,
• Size of the building.
32

28.
Wind load
 Most
important factor that determines the design of tall
buildings over 5 storeys, where storey height
approximately lies between 2.7 – 3.0 m
 P=k1*k2*k3*vz^2
 Designed
as per IS 875 PART (III)
 Taking v=50 kmph

29.
Lateral forces
 High
wind pressures on the sides of tall buildings
produce base shear and overturning moments.

 These
forces cause horizontal deflection
 Horizontal
drift
deflection at the top of a building is called
is measured by drift index, ∆/h, where, ∆ is the
horizontal deflection at top of the building and h is
the height of the building
