Note
1 When a number of elements are assigned a
single Member, the Member number retains the smallest element number.
That element then becomes the representative element. All design parameters
for the Member must be input for the representative element.
Note
2 If the elements to be assigned a Member retain
different material and section properties, or the directions of the node
connections are different, a Member can not be assigned.
Note 3 The design parameters,
Effective Length Factor (K), Equivalent Moment correction Factor (Cm),
Moment Magnifier (B1/δb,B2/δs) and Limiting Slenderness Ratio
are taken from the representative element, and Unbraced Length (L,Lb)
is taken from each element.
