Thank you Leonard. I can not get the paper from ARCHITECTURAL INSTITUTE OF JAPAN. I will check into it when I have chance.
Thank you Tom. I found difference in my problem. As you said, Compress uses AISC and PVElite uses WRC107 to calculated supporting legs. The results are "apples and grapes"...
I ran into a problem. Same vessel designed with both sw came up different results! Major different is in the leg design with seismic load.
Can any one offer an opinion? compress or pvelite?
