11. 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.

32. 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

33. 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
3333

34. 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, D/h, where, D is the
horizontal deflection at top of the building and h is
the height of the building
