<\/a><\/p>\nI reviewed the available forums and videos and understand the complexity of a reinforced concrete simulation. In this context, I reviewed configurations of solid elements for concrete such as: solid65, CPT195, and solid 185 and line type elements for reinforcement bars using beam, link and reinforcement type elements.
I have followed recommendations by @Wenlong in the forum ttps:\/\/forum.ansys.com\/forums\/topic\/error-contact\/ for the use of the EREINF command, geometry slices with merge topology and other recommendations given in “Modeling Rebar Reinforced Concrete on Workbench.pdf”<\/p>\n
Other recommendations from the forum \/forum\/forums\/topic\/error-with-reinf264-elements\/ by @gigihmprayogo to use CPT125 elements for concrete and model the reinforcement bars using solid type elements.<\/p>\n
Some other recommendations from @peteroznewman to generate the correct meshing of solid type elements along with line type elements from the forum \/forum\/forums\/topic\/solution-not-converged-metric-rc-beam\/.<\/p>\n
And other forums with information relevant to the application of loads, meshing and concrete modeling have helped me learn something about Ansys.<\/p>\n
One of the problems that worries me is the joint behavior of concrete and reinforcement bars when applying cyclic loads, and adding that the concrete will be crossed by a steel beam, its complexity will increase. It is an interesting challenge that I would like to be able to carry out.<\/p>\n
I have reviewed some concrete behavior models such as the “microplane material to model concrete damage” Druker-Prager, Menetery-William, and bilinear concrete models recommended in the “Concrete Material Model” forum.<\/p>\n
These are my questions:
I would like to consider Mander’s model in modeling concrete reinforcements. Mander’s model for concrete behavior idealizes the behavior of concrete confined by reinforcing steel. I would like to be able to apply this concrete model through bilinear behavior.<\/p>\n
In this sense, is it possible to change the material within a model to consider the modeling results in the elastic stage and then change the material for the inelastic stage? I mean, apply conditions to adjust the behavior of materials through commands.<\/p>\n
Due to the convergence problems that can occur when having multiple materials, I would like to ask you about recommendations on the use of combined materials for modeling concrete and reinforcing steel.<\/p>\n
Lastly I would like to receive any recommendations: in considering the implementation of non-linear spring like Combin39 for the contact between the reinforcement bars and the concrete to aid convergence, slip interaction between reinforcement bars & concrete (NOT full tied ), and adjust shear reduction coefficient. in Solid 65 model command, mentioned by @abdalla and Dr. \/ Abdalla Mohamed respectively on \/forum\/forums\/topic\/cyclic-loading-from-ansys-workbench\/<\/p>\n
Any recommendation to open another new Discussion will help me as well.<\/a><\/p>\n","protected":false},"template":"","class_list":["post-355970","topic","type-topic","status-closed","hentry","topic-tag-apdl-command","topic-tag-bond-slip","topic-tag-bond-slip-behaviour","topic-tag-combin39-1","topic-tag-concrete-material","topic-tag-concrete-non-linear","topic-tag-drucker-prager-model","topic-tag-hysteresis-loop","topic-tag-menetrey-william","topic-tag-microplane-model"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
