Dear Dr Subramanian, 

I started a new thread but am responding to your  mail in the precast one. 


Thanks fo rthe references. I think they  are  perhaps  dated, esp with regard to shear wall behaviour . Our understanding of shear wall behaviour has undergone a sea change in past 5-10 years. The spurt of earthquakes  has given us a lot of new insight into their performance- especially  the 2010 Chile earthquake and the 2011 Japan and NZ earthquakes 
Of particular concern has been the compression buckling of walls seen in these earthquake due to lack of boundary element confinement (large spacing of hoop steel) 
pl see the foll paper:

best regards,
