HI i created a built up section using Section wizard. while analyzing my model, i receive a error message that, ***ERROR*** IX MISSING or SMALL FOR MEMBER 1
How to rectify this issue.
It suggests that the sectional property Ix for that member is small or missing. can you please upload the file here for investigation?

HI i attached the staad file along with the UPT file I created for section.
The value of Ix is zero in the .upt file. Check and change the value accordingly. For sections exported as general one, program does not calculate only the shear area. But it calculates Ix. If you are using any old version please use 22.01.00.39 version of STAAD.
HI, thank you for your valuable reply. I don't know how to check IX value in UPT file,. Instead i created a new UPT file with different name and ensured the properties before save the file, but still i am using the same problem. My staad version is 20.07.11.70
If you have exported a general section upt, open .upt file with notepad, you will note that there are 16 values, 8th value is IX.
Try smaller unit while exporting to get non zero value.
