The highly popular model namely Mander’s model is used for concrete stressstrain relationship since it is simple and effective in considering the effects of confinement. The module determines the expected behavior of a user-defined cross-section by first dividing the section into a number of parallel concrete and steel “fibers”. Then, the section forces and deformations are determined from the fiber strains and stresses using fundamental ...
