Annotation: The article discusses the possibilities of covering rectangular large-span roofs with on-standard side ratio with the help of the MARCHI structural system. The basic information about the typification of the main structural members of the MARCHI for rods and joint-connectors are given. The approaches for regulating the basic parameters of the stress-strain state (SSS) of the designed system are offered. Their realization allows to use typical structural elements of the system to cover the non-standard spans. Analytical dependences for appointment of basic parameters (relative height of roof h/l, relative bump of roof f/l) are suggested and the basic dependances of changing SSS parameters of the being designed roof depending on the design parameter change are considered.
Keywords: large-span structural root, system of MARCHI, stress-strain state, typification, unification.
Pages: 5-14.
