The presented article deals with flat roofs of triangular trusses with the development of the structural form in one longitudinal direction. Bearing structures of trihedral trusses are used for public and industrial buildings and constructions. Using the modular system as a result of cross structural division of the structures of triangular trusses allows to carry out their safe transportation to the place of storage or construction. The peculiarities of formation of the modular system taking into account structural peculiarities of the layout of spatial trihedral trusses are considered. By the results of a comparative analysis of the deformability of mathematical computational models of three-sided trusses in the roof, the use of pliable module coupling assemblies was substantiated. The possibility of using different element composition of rods within each module of a triangular truss is confirmed.

Keywords: modular system of a trihedral truss, structures of non-centered truss-less knots; spatial-string computational model; deformability of modular systems with rigid and compliant mounting knots, comparative analysis of computational models
