Cohesion value for stability analysis of dams

4 posts in this topic

While performing stability analysis of dams, we have a "shear friction factor" for which we need cohesion value of the material. I am confused that whether i should use cohesion value of concrete or the rock foundation? What is the cohesion value of 3000 psi concrete and how to calculate it? In the book of santosh kumar garg, he has used the shear strength of joint instead of cohesion. Why is that? Because many other books use cohesion in the formula.

you can use the uniaxial compressive strength of concrete or rock which ever is smaller. If u want to use the cohesion value u can take the half of compressive strength which is equivalent to cohesion.thanks
