after applying floor diaphragm I am getting instability warning at mater joints
please check my model and tell how to remove this warning2061.major1 Wind.STD
Hello,
I did a lot of investigation and then found the issue. From level 23.1 to the top if you see the actual coordinate it 23.1001 instead of 23.100. If you double click on any node you will not find that but if you double click on any beam and check the same you will be able to see that. I have just shifted that part 0.0001m in negative Y direction and ran the file. It ran well. the instability was due to the location centre of mass reported out of plane. Please see the reference file. Also you can do the same steps in your original file and check the issue. hope this helps.
Thanks!!
