Description
Summary:Combined stayed roof with the span equal to 60 m is considered as an object of investigation. The roofs framework is formed by two groups of structural members, which are placed in longitudinal and transversal directions. The frames, which are formed by the trusses and columns, are placed in transversal direction. Structural steel S355 is considered as a materials of all rigid members – pylons, columns and girders. Three variants of materials for suspenders were considered. The dependences of materials consumption and main geometrical parameters of combined stayed roof were obtained for three above mentioned variants of suspender materials were obtained on the base of numerical experiment. The numerical experiment was carried out by the program LYRA 9.4. It was stated, that the rational values of suspenders amount, transversal frames bay and height of pylon are equal to 8, 6 m and 18 m, correspondingly.
