Transcript of Earth Quake Load
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

Walls : 230mm Thick WallMaterial Properties
Concrete : All component unless specified in Design M25 grade all
