Types of buildingsTypes 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 loadwind 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
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
33
33
High wind pressures on the sides of tall buildings produce base shear and overturning moments.
These forces cause horizontal deflection
Horizontal deflection at the top of a building is called drift
Drift is measured by drift index, /h, where, is the horizontal deflection at top of the building and h is the height of the building
