Re: steel project Hello; In your project, there were too many crosses on top of each other in the beams between the cross members and the 6-7 axes. Therefore, analysis could not be performed. When these elements are deleted, there is no problem. In the analysis settings, the ductility level is normal and it is sufficient for this project to get Rx and Ry of 5. Otherwise, your column sections do not comply with the high ductility level requirements of the Earthquake Code. Divide your lovers at all intersections with the divide command. Use U profiles as purlin section, not IPE section. In column - truss connections, make a movable connection, not a fixed one, in the axes 2-3. Your column-beam connection in the weak axis is suitable, but the most frequently used connections are single-slip plate or gusseted connections. Conflicts that start with TRS, which is at the top of the conflict control, are caused by the absence of a junction in the truss ridge region in the program. You can't solve it, skip it. When you click on the other joint overlaps, it will direct you to the area where the error occurs. You will see two red colored elements, the junction bolt and the curved region of the beam head with the body overlap, increase the distance between the bolts, the d parameter. You should also examine other conflict errors and produce similar solutions. Good work.
