Restoration of the Bearing Capacity of Damaged Transport Constructions Made of Corrugated Metal Structures

The paper deals with damages of transport constructions made corrugated metal structures in the body a railway track or road during their operation. A constructive variant to restore bearing capacity was developed, which consists installing an annular stiffening rib into concave part profile. main advantage this method compared double corrugating is possibility performing reinforcement works structure operation without interrupting movement vesicles. study has proved that significantly increases carrying structures. numerical finite element model developed determine stress-strain state reinforced round ribs. soil pressure on shell taken account application radial and axial forces outer surface shell. It determined most appropriate location ribs centre building, where area corresponds width line. approach ability more efficiently distribute material by selecting loaded sections
