Connection type is body-ground. One edge of beam connection(body side) is on top edge of bolt hole in structure while other edge(ground side) is taken&nbsp;with geometry reference of bottom edge of bolt hole in the similar structure. I have put an offset of 2mm in Z direction(gravity direction) at ground side of this connection to bring gound side out of the&nbsp;structure . Both sides(reference and mobile) are set deformable&nbsp; All four beam bolt connection are modeled in similar way. A pretension of 8000N is applied on each beam bolt. 3 steps are used in analysis. 1st for pretension,&nbsp;2nd for lock and&nbsp;3rd&nbsp;for structural load.<\/p>\n<p><\/p>\n<p>In solution,&nbsp; whole structure went 700mm into the direction of gravity and also whole structure stretched. Beam bolt are still physically shown connected to the edges but stretched from ground to the body. I cannot figure out what is wrong with the system. Either beam bolt connection not worked well or huge pretension did this large deformation<\/p>\n","protected":false},"template":"","class_list":["post-32838","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["5010"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["4360"],"_bbp_subscription":["238369"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["32838"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","161753"],"_bbp_voice_count":["2"],"_bbp_reply_count":["14"],"_bbp_last_reply_id":["76678"],"_bbp_last_active_id":["76678"],"_bbp_last_active_time":["2019-02-03 00:32:04"]},"test":"raheel"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/32838","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\/32838\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=32838"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
