Turkish Hello. I think there are 2 problems when I use the Modify->Rotate Structure command in Idestatic version 7.017. The first is that Rx and Ry are not automatically changed. The second is that the polygon columns in the structure exceed the Maximum Pursantage when all of the polygon columns are analyzed after rotating the structure. I guess the program does not change the Ix and Iy of the columns. This problem was solved when I drew again and created a polygon column. I haven't tried version 7.018 yet, is this problem solved?

Hi, I can change the structure from 0 or 90 degrees angle When you turn with , it is an expected result that different end force will come out from 0 and 90 degrees position because 5% earthquake eccentrics are applied according to 0 and 90 degrees global coordinate system. We expect it to be the same when the earthquake impact angle can be given in the program. 2nd. When all of the polygon columns in the structure are analyzed after rotating the structure, it exceeds the Maximum Pursantaj. I guess the program does not change the Ix and Iy of the columns. This problem was solved when I drew again and created a polygon column.[/quote] Local axes of polygon columns can be at any angle. Inertia is always found automatically for the major and minor directions in the program. As it will be understood by my response to the first situation, when you rotate the structure, the local axes of the column will also change according to the earthquake impact angle. In my experiments, I saw that the inertia values do not change after rotating the structure, but since the angle of the element's local axis and the earthquake direction will change, the extreme forces will also change. You can test the situation I wrote in a structure rotated 0, 90 and 180 degrees. However, if you add the project, we can look at the situation you wrote in more detail."obguner":owsp71nt" said:I think there are 2 problems when I use the Modify->Rotate Structure command in ideological version 7.017.

I entered 270 degrees. I should have said it can automatically change Rx Ry in 90 and 270 degree rotations. I tried 90 degrees again, but still faced the same problems. This is the 4th block I tried. I couldn't manage to attach the file here and I'm sending it from my Google Drive account.

Thanks for your report. .."obguner":3nt8vuyv" said:I tried 90 degrees again, but still faced the same problems. This is the 4th block I tried. I couldn't manage to attach the file here and I'm sending it from my Google Drive account.You do not have permission to view link Log in or register now.
