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,
Alpa Sheth�
