DESIGN OF SEVEN STOREY BUILDING

Live Load : 2 kN/m²

Live Load : 1.5 kN/m² ( Terrace )

Floor Finish : 1 kN/m²

Water Proofing : 2 kN/m²

Wind Load:

Earthquake Load : As per IS:1893(Part-1)-2002

: 3 m

Type of soil :

: 28.5 kN/m²

:

Storey Height : 3m ( For Each Floors)

Floors : Basement + Seven Floors

Plinth Level : 6'6"

As per IS:875(Part-2) - Not Design for Wind Load, Since Earthquake Load is exceed the Wind Loads
