I need to model the behavior of high strength concrete, meaning concrete with a minimum strength of 90 MPa. Does anyone have data for high strength concrete behavior? - I did manage to derive values from equations I found in papers, but this is incorrect material data and it does not behave according to theory as the equations are meant for normal strength concrete. If anyone has data for high strength concrete it would greatly appreciated.
Dear Ruslan,
several manuscripts published of-late describe modeling of normal as well as high-strength concrete using the concrete damaged plasticity (CDP) model. The characteristic parameters of the CDP model are required to be suitably chosen appropriately to mimic the real behavior of normal and high-strength concrete.
Several questions have been asked and answered in ResearchGate in this context, e.g. https://www.researchgate.net/post/Need_background_on_the_7_Parameters_in_Concrete_Damaged_Plasticity-Viscosity_Dilation_Angle_Eccentricity_K_fb_fc_tension_and_compression_recovery
You may check if by tuning these seven parameters of the CDP model you are able to capture the realistic behavior of the intended high-strength concrete as close to the experimentally obtained results as possible.
Hope this would help you in proceeding ahead in your research. All the best.
With best regards,
Vasant Matsagar.
Dear Ruslan
Have a look to this video

Article Nominal flexural strength of high-strength concrete beams
Article Nominal axial and flexural strengths of high-strength concrete columns
Please take a look at these two articles hope it can help you with your data.
Dear Ruslan,
Starting with a simple equation for generating data then tweaking the CDP default parameters will help you calibrate.
Good luck.
