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.<br \/>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&nbsp; &ldquo;Modeling Rebar Reinforced Concrete on Workbench.pdf&#8221;<\/p>\n<p>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<p>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<p>And other forums with information relevant to the application of loads, meshing and concrete modeling have helped me learn something about Ansys.<\/p>\n<p>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<p>I have reviewed some concrete behavior models such as the &ldquo;microplane material to model concrete damage&rdquo; Druker-Prager, Menetery-William, and bilinear concrete models recommended in the &ldquo;Concrete Material Model&rdquo; forum.<\/p>\n<p>These are my questions:<br \/>I would like to consider Mander&#8217;s model in modeling concrete reinforcements. Mander&#8217;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<p>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<p>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<p>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 &amp; 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<p>Any recommendation to open another new Discussion will help me as well.<a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/07-03-2024-1709842001-Picture2.jpg\"><img decoding=\"async\" title=\"Rc Column and Steel Beam Connection3\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/07-03-2024-1709842001-Picture2.jpg\" alt=\"\"><\/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":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["72401","99"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_bbp_likes_count":["1"],"_btv_view_count":["560"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1709842745:282734"],"_bbp_topic_id":["355970"],"_bbp_forum_id":["27791"],"_bbp_engagement":["99","72401"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["357166"],"_bbp_last_active_id":["357166"],"_bbp_last_active_time":["2024-03-14 18:46:29"]},"test":"jrmasapanta1espe-edu-ec"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/355970","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":3,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/355970\/revisions"}],"predecessor-version":[{"id":355973,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/355970\/revisions\/355973"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=355970"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
