Dear ganini, without seeing your model, it is very hard to guess the problem source. Please check the boundary conditions (e.g., is it not possible you apply a fixed support on a surface, blocking rotations which are allowed in reality?). Then, please send us your model along with your ATENA User ID (WR), the L-D graphs, and a sketch and/or photo of the experimental setup. Also include the material info you have (measurements, manufacturer data, ...).

Dear software developer:
I have to simulate the reponse of a beam subjected to reversed cyclic loading. The beam is a steel reinforced concret beam or steel reinforced SHCC beam. But when I choose 3D Nolinear Cementitious2 to define ordinary concrete and 3D Nolinear Cementitious 2 user to define SHCC in ATENA 3D, I cannot get good results(load-deformation behavior, stiffness degration) compared to the test results. So, what should I do to choose a suitable material to simulate the cyclic behavior of concrete or SHCC under reversed cyclic loading? or can I solve the problem in other ways? Thank you!
