After preparing the Robot file and customizing project data, the video proceeds to model the main portal frame. This can be done in 3D or by using 2D views or captures for easier modeling. The presenter chooses the XZ plane and the Y=0 line to facilitate drawing the portal frame.
The video demonstrates how to define the profiles for the columns (360) and beams (330) of the portal frame. It then shows how to display these profiles to visualize the modeled structure.
A crucial point is emphasized: uniformizing the orientation of the local axes for different profiles. This is important to obtain consistent moment data. The presenter explains that an inconsistent Z-axis orientation can lead to moments being interpreted differently (e.g., positive outwards vs. positive inwards). To correct this, mirroring or changing the orientation of the column is suggested, with a vertical mirror being demonstrated as a solution.
The next step involves setting up the supports for the portal frame. The presenter applies fixed supports (encastrement) and stresses the importance of verifying that all directions are locked, as accidental deactivation of a direction can occur.
The video then shows how to copy or translate the modeled portal frame four times to generate the complete set of portal frames for the hangar. This involves using the translation tool in the Y-direction with a specified distance (0.60) and four copies.
Finally, the project is saved, and an analysis is performed to verify the structure for any errors. The presenter advises regularly checking the structure during the modeling process. This proactive approach helps in easily identifying and correcting any errors as they arise, pinpointing the specific elements causing the issue.
