hi,
my name is Kiran. im a M.Tech student from india specialised in Nuclear engineering. Now I am working with a project on "internal overpressure test of a concrete containment building". i have made a simple axisymmetric model of a containment building with pre stressed concrete as the material without any reinforcement. But im having problem while running the job as it asks for more than one value on the shear retention curve. I have chosen elastic and brittle fracture properties for concrete. can Someone help me with this problem? What shear retention factor should i give and why it is asking for more than one value?
