    Metods to Assess Bearing Capacity of Corrugated Metal Structures
    (Тернопільський національний технічний університет ім. Івана Пулюя, Тернопіль, 2016) Luchko, Josef; Kovalchuk, Vitalii V.
    EN: The aim of the research is to analyze the methods of calculating and evaluation of the bearing capacity of corrugated metal structures (the CMS) in cooperation with soil backfill as a result of stress from rolling stock or vehicles. To prove the applicability of these methods for the calculation of pipes of different diameters and different structural forms. The methods of calculating the deflected mode of corrugated metal pipes of small diameter (up to 3 m.) at constant load, and calculation methods CMS of large diameter more than 6 m are analyzed. The calculated models that take into account the spatial work of structures is more correct than " flat " models and calculated scheme, and therefore the calculation of the CMS is to apply three-dimensional calculation model which model the most realistic work of corrugated metal structures. For the first time the methods of calculation and experience designing of flexible corrugated metal structures at interaction of soil backfill and under the influence of the stress from the rolling stock and road transport are analyzed. The obtained analysis of the evaluation methodologies of the bearing capacity of corrugated metal structures of different shape section can be used by engineers in bridge probationary stations Ukrainian Railroad (UR) and Ukravtodor and project organizations involved in the design and construction of the CMS.
