Hello, I am working on large girders with openings in its web, In my model results, I see unexpected large stresses on some points due to the singularity of the point, does anyone know how to remove this problem, Shahid

Hi, I am working on large I-girder steel structure with different openings in its web, I have attached four springs on four corners of the structure when looking from front. I need to verify the forces in the spring, for stiffness I used 1, I also dont know about its exact units, as maual calls...

units of shell edge load are N/mm. So its force per unit length.

Hello, I am working on simple model, a large rectangular plate having different openigs, i want to study the shear case, I tried to apply shell edge load on four sides, but i dont know how to calculate the magnitude as length and height of the plate are different. shahid
