Re: Seismic Zone For India

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The Indian Code that is applicable for earthquake analysis is IS1893,
that was last revised in 1984. The wind load code is IS875, last revised
in 1987.  There are many factors to be considered, and it is best 
that you get a copy of these codes.  Most structures in India are 
required to comply with the relevant IS codes, and you should check if 
this situation is also true in your case.  Some of the codes that you
would need to comply with (assuming RCC structure) are IS456, IS875 
(all parts), IS:1893, IS:4326, IS13920 for the structure, and 
several others for foundation etc.

Hope this helps.
