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
