https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/131698/wind-load-in-direction-of-skewed-gridA portion of the building I am designing is skewed at a 7-degree angle. The braced frames that are in the skewed portion are experiencing large out-of-plane drift, which I assume is caused by the wind load being applied in the orthogonal direction, ratheren-USTelligent Community 12https://communities.bentley.com/thread/401933?ContentTypeID=1Mon, 13 Feb 2017 15:47:52 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:09b79e0a-bbf2-4414-91c3-69337230f9bcSeth Guthrie<p>For Ram Structural System, you can specify any plan angle when using Wind (or Seismic) User Defined Story Forces, but the code-specific, program generated loads are based on the global axes. &nbsp;For more see: <a href="https://communities.bentley.com/Products/Structural/Structural_Analysis___Design/w/Structural_Analysis_and_Design__Wiki/ramss-wind-loads-faq.aspx">communities.bentley.com/.../ramss-wind-loads-faq.aspx</a> &nbsp;If you are using a flexible diaphragm type, then it will be important to apply the loads in the plane of the frames to prevent large out-of-plane deformation.</p><div style="clear:both;"></div>
