Annotation: The article deals with the additional features overlapping rectangular span roofs with non-standard aspect ratio with the help of the structural type of the MARCHI system. The results of the analysis features of constructive solutions, examples of use, basic calculation methods, the requirements of domestic and foreign regulatory documents on their design and construction have been given. Based on the results of the analysis the issue it has been highlighted the problems arising in the design of structural designs on non-standard plans. To the study of atypical aspect ratio of the structural coverage in terms of (the aspect ratio a / b) and appropriate approaches to ensure that the regulation of the stress-strain state of structural system by varying the basic geometric parameters of the study design have been suggested. It has been considered and taken into account the factor of the impact of various snow load value on the stress-strain state of the roof, set the overall patterns of change in the stress-strain roof status on a rectangular non-standard terms (with the ratio of the lengths of the sides 1 / 1.6… 1 / 2.4), depending on the changes proposed by the geometrical and other important design parameters.
Keywords: large-span structure roof system of MARCHI, the stress-strain state, typification, unification.
