DESCRIPTION:The concept of ‘structural connectivity’ is introduced to 
 assess the connectivity of structural trusses and road networks\, which ar
 e examples of two-dimensional assemblies. Metrics for such connectivity\, 
 and also for identifying the least connected members and zones\, are deriv
 ed from an adaptation of the ‘Bristol approach’ (based on joint stiffn
 ess)\, Newman’s method (based on network theory)\, and Route Structure A
 nalysis (developed to analyse road networks). Fractal\, Warren and Fan-typ
 e trusses of the same triangular outer shape but differing internal geomet
 ric configurations were analysed using all three approaches\, both to expl
 ore similarities across metrics and to find the best connected truss. Alth
 ough the different measures gave somewhat different results for the same s
 tructure\, there was some degree of consistency\; thus enabling the Warren
  truss to emerge as the best connected configuration. The metrics indicate
 d that truss ends and chord members were the least connected areas and mem
 bers\; but that increasing the axial rigidity of chord members improved th
 e connectivity of all truss forms. An idealised ‘Class A’ road network
  in Sri Lanka was analysed\, using a combination of Newman’s method and 
 Route Structure Analysis\, as proof that the concept of structural connect
 ivity could be applied to assemblies other than engineering structures.\n\
