NOTE 2 The ability of a steel structure to absorb deformation is related to both th
32、e elongation and the toughness properties of its constituent steel products. The global performance required depends on the anticipated deformations. The local performance required depends on the details used. Due to higher stress levels, structures of steels according to Tables 1 and 2 require spec
33、ial care in both the control of deformations EN 1993-1-12:2007 (E) 6 and in detailing to avoid notches and other stress concentrations.

47、The rules for semi-rigid joints are not applicable for steels with grades greater than S460 up to S700. If non-linear plastic global analysis considering the partial plastification of members in plastic zones is used, connections between members shall only be on the basis of full-strength joints. If
