Determination of the problem boundaries

When these two concepts were examined, the Author realized that several attributes were necessary to discern between these two concepts. The attributes would become later a part of the morphological table and would be used in Step 2.1, Identification of symbolic attributes. The following symbolic attributes and their values were identified  

A Direct connection upper flange-column None,yes 

AjWeld type for direct connection upper flange-column None,fillet, butt, other 

A 7 Connection angle seat-column None, bolts, welds 

The numbering of attributes is consistent with the morphological table (see Table 6.2).
