I am beginner in ANSYS. I am analyzing a column that is connected to the base by welding as can be seen below. I applied 300 mm z-direction displacement on the top face of the column and added fixed support at the bottom face of the base. I assigned every connections. Now, I want to draw a load-displacement curve to verify the experimental results. The reaction force from the displacement and the directional deformation at the z-axis of the top edge of the column were used to derive the load-displacement curve. However, the load keeps increasing rather than going down after reaching the ultimate load as in the experiment. I defined the nonlinear properties of the used steel by assigning isotropic multilinear hardening. What can be the problem?<a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/11\/16-11-2022-1668582409-1.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2022\/11\/16-11-2022-1668582409-1.png\" alt=\"\"><\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-240951","topic","type-topic","status-closed","hentry","topic-tag-displacement-load-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["267895","88"],"_bbp_author_ip":["23.220.96.181"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1242"],"_edit_lock":["1668583754:197131"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["240951"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","267895"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["241330"],"_bbp_last_active_id":["241330"],"_bbp_last_active_time":["2022-11-18 10:28:27"]},"test":"didar-meiramovalumni-nu-edu-kz"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/240951","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":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/240951\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=240951"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
