Re: opinions questions about using ideCAD Steel 8 Hello; There does not appear to be any modeling problem in your project. There is no problem in terms of analysis and design. In the structure you entered and designed, you provided the stability with moment transferring frames. However, another steel carrier system design where you can provide stability more appropriately is 'Central Braced System'. Due to the structure of this system, you can use braces to provide vertical and horizontal stability. It is especially important that you provide stability in the lateral direction on the roof. Floor displacements report is created if there is a diaphragm in the structure. Since you do not have any slab entrance, you have to control the displacement of the structure yourself. As in this project, in structures that do not contain diaphragms and in random structures; As in other programs, the engineer himself has to control the floor displacements. If the formulas specified in DBYBHY 2007 Section 2.10 are used; If we check the UX displacement of the S01 column in the EX loading on the A-1 axis; Before obtaining the drawings, be sure to enter all combinations and check for overlap. Good work.
