Reliability assessment of the behavior of reinforced and/or prestressed concrete beams sections in shear failure

The object of this article is to be able to simulate the behavior of reinforced and/or prestressed concrete beam’s section in the shear loading through a model allowing the evaluation of nonlinear strains caused by shear, while taking into account the real behavior of the materials. In this approac...
