I just performed a Modal analysis, and it does not seem very off (graph attached for the 12th modes &#8211; 3.2499Hz); also, the participation factors seem fine. Since the same problem still persists, may I ask if it could be because of material properties? I changed many combinations to try to address this. I am now using &#8220;Structural Steel&#8221; for all beams and &#8220;Concrete&#8221; for all solid bodies. Both materials are from Ansys General Material.&lt;\/p&gt;&lt;p&gt;&lt;br&gt;Again, thank you.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Best,&lt;\/p&gt;&lt;p&gt;Ted&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/06\/20-06-2023-1687305294-Bridge1.png\" alt=\"\" width=\"787\" height=\"463\" \/>\\<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/06\/20-06-2023-1687305316-Sheet.png\" alt=\"\" width=\"800\" height=\"446\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-289650","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/289650","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/289650\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=289650"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
