I have a 45&#39; tall structure with a partial mezzanine. The roof is modeled as semirigid and the mezzanine is modeled as rigid. The mezzanine area has moment frames while the full height areaen-USTelligent Community 12https://communities.bentley.com/thread/545721?ContentTypeID=1Wed, 25 Sep 2019 21:03:29 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:33d93714-b294-434f-b6fb-57c38961f573Seth Guthrie<p>I keep everything connected to the diaphragm and design the beams using a hand check assuming axial compression = (change in frame story shear) * (beam length) / (frame length).&nbsp;&nbsp;</p><div style="clear:both;"></div>https://communities.bentley.com/thread/545719?ContentTypeID=1Wed, 25 Sep 2019 20:58:07 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:e59370ad-038a-4d7f-a573-49ae039ac15bChad Simms<p>The diaphragm at that level is a rigid diaphragm. What is your recommendation for calculating axial loads in these beams? The axial loads shown seem much higher than I would expect. It seems like axial load is accumulating as you move right instead of axial loads being taken to the foundation through shear in the columns.</p><div style="clear:both;"></div>https://communities.bentley.com/thread/545715?ContentTypeID=1Wed, 25 Sep 2019 20:50:58 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:b564c396-854d-4b42-914a-fc8b59188687Seth Guthrie<p>If there is a diaphragm there then some of the unbalanced force could be in the diaphragm. Furthermore, if it&#39;s a semi-rigid diaphragm then there could be an applied external point load at that location.&nbsp;</p><div style="clear:both;"></div>
