I was performing a cyclic hollow pile to pile cap connection using ABAQUS, I use concrete damage plasticity (CDP) and static general analysis in my model. Some videos on youtube suggesting that since I use CDP which has a softening branch, the static general analysis will not included the CDP parameters I input. You can watch on the link below at minute 10.00 for detailed information. Should I use a static of dynamic analysis?

It is safer to use a dynamic analysis in this case. I would recommend a dynamic analysis to be performed.
Concrete Damage Plasticity (CDP) is typically used to model the nonlinear behavior of concrete, particularly its ability to undergo cracking and damage. While CDP is commonly employed in dynamic analyses, it can also be utilized in static analyses depending on the specific objectives and conditions of the analysis.
In the context of your pile to pile cap connection analysis using ABAQUS, it's important to consider the loading conditions and the behavior you aim to capture. If the cyclic loading you are applying in your analysis represents realistic loading conditions, a dynamic analysis may be more appropriate. Dynamic analyses are well-suited for capturing the time-dependent behavior of structures subjected to cyclic loading or dynamic events.
On the other hand, if the cyclic loading you are applying is relatively slow or if you are primarily interested in the equilibrium behavior and response of the structure, a static analysis can still provide meaningful results. In a static analysis, the CDP parameters you input in ABAQUS, including the softening branch, can be considered, as the analysis aims to reach an equilibrium state under the applied loading conditions.
It's important to note that the suitability of a static or dynamic analysis depends on the specific characteristics of your problem, the loading conditions, and the behavior you want to capture. If you have concerns about the accuracy or appropriateness of your current analysis setup, it is advisable to consult with experts in the field or seek assistance from ABAQUS support to ensure you are using the appropriate analysis approach for your specific case.
