| Abstract: | Through experiments on 3 models and corresponding analysis by FEM, the regulations of the stress round about the cracks of welded steel crane\|girders subjected to eccentric and concentrated loads were studied, and it is the respective cycles of shear and main tension stress in web that lead to the crack development of upper part of the crane\|girders. |
