Janak,
There are couplers available and are being used widely in US and UK. I have done a few projects where such couplers are used effectively. You can use LENTON make couplers. You can visit their site and get more information based on your specific requirement.
Regards,
Vikas

roark.sol@spectranet.com wrote Dear Janak,
If you refer to table 7 of IS-1893-2002, you will notice that R is high for ductile detailed systems in comparison to non-ductile detailed systems. This implies that ductile detailing is ACTUALLY A MORE ECONOMICAL SYSTEM for designing seismic resistant structures. If you study this table with care, all your queries related to the ductile detailing will be resolved.
Regards
Pankaj
