Correlations of stiffness with spt N value for the HS model

Question

Hi all, 
 If anyone knows the stiffness correlation based on SPT N value, please share. 
 and 
 any correlations with stiffness also please share. 
 Thanks.

Dear Nitha, 
 For stiffness there is no reliable correlation from SPT. SPT is primarily to determine strength parameters... Be aware that correlations may be quite accurate, or may be just an average of a wide scatter of values. Hence, reality maybe somewhere in between 0.25 and 4 times the correlation value. 
 With kind regards,
