5.1.3 Rigid-plastic global analysis

(1) The joints should be classified according to their strength, see 5.2.3.

(2) For joints connecting H or I sections Mj,Rd is given in 6.2.

(3) For joints connecting hollow sections the method given in section 7 may be used.

(4) The rotation capacity of a joint shall be sufficient to accommodate the rotations resulting from the analysis.

(5) For joints connecting H or I sections the rotation capacity should be checked according to 6.4.

5.1.4 Elastic- plastic global analysis

(1) The joints should be classified according to both stiffness (see 5.2.2) and strength (see 5.2.3).

(2) For joints connecting H or I sections Mj,Rd is given in 6.2, Tj is given in 6.3.1 and ^Cd is given in 6.4.

(3) For joints connecting hollow sections the method given in section 7 may be used.

(4) The moment rotation characteristic of the joints should be used to determine the distribution of internal forces and moments.

(5) As a simplification, the bi-linear design moment-rotation characteristic shown in Figure 5.2 may be adopted. The stiffness modification coefficient // should be obtained from Table 5.2.
