Thank you very much for your help. It worked. Wish STKO better and better!

Dear STKO Team
Hello, I have built a quasi-static analysis model of bridge piers. The ECC01 material cannot be tested, and the operation result shows that the source file cannot be called. What is the problem?

I have improved the tensile breaking energy according to your suggestion. Due to the shape of DamageTC3D tensile curve, it can only be simplified to a double broken line model. In addition, the compression constitutive is adjusted to be close to the material property test results (Figure1, 2 ...

Thank you very much for your reply. We have tried the method you mentioned to improve the breaking energy. See the following figure for specific parameter Settings. But it didn't work as well as we expected. The component damage was much less than expected. We guess that it may be caused by the lack ...

What I want to build is a short column compression model, which should not use shell elements. The constitution of CDP concrete in ABAQUS can customize the skeleton curve. Is there any nD material in STKO that can customize the skeleton curve?

Dear STKO Team
First of all, thank you very much for helping me solve the modeling problem before.
At present, I have encountered great trouble in the material constitutive definition. I hope to get your help again. Thank you in advance.
ECC is used for concrete in my solid model. I browsed a lot of ...

Hi, I have made a preliminary modification to the buckling model. Stirrups and concrete use 'ASDEmbeddedNodeElement', longitudinal reinforcement and concrete use 'BeamTosolidBarslip'. It's worth noting that I set up a uniaxial material with a lot of stiffness so that it doesn't stick slip. But I ...

Dear STKO Team
Model overview: The buckling behavior of longitudinal reinforcement in rectangular concrete columns is simulated. Section size: 200mm*200mm; The longitudinal reinforcement is HRB400 steel bar with diameter of 16mm, and the diameter of stirrup is 12mm. In order to simplify the model ...
