Concrete Bearing

Jul 22, 2009· As the concrete is compressed in one direction, it wants to spread in the orthogonal direction, but can't because of the restraining surrounds. I disagree with AHaddad1 that it is related to "shear cone" failure. Bearing failure in concrete should be thought of as a crushing failure, while shear failure is a diagonal tension failure.
