Hi,

I am new in ABAQUS. I tried a lot to find the critical lateral torsional buckling moments from ABAQUS for simply supported Steel I beams. I modelled an I beam with shell element and define the sections. I meshed it by number. Then I did buckle analysis with 4 eigen values in step part. I create boundry condition as a simply supported beam using those node of after meshing and I also applied uniform moment at two end.

But, how do i find the critical moment for LTB? Again, is there any procedure to follow? 

Thanks in advance.
