Abstract
The relevance of the work lies in the fact that properties of damaged structures were sufficiently studied. Therefore, there is a high risk of their unpredictable behavior, which can lead to malfunctions, including serious accidents and man-made disasters. The risk of such danger increases significantly in the extreme climate of Siberia and the North. Damage and destruction of structures are confirmed by many facts.
Purpose: The aim of the work is to experimentally simulate the bridge bearing capacity after damage in order to understand how the bridge behaves in various conditions and what measures can be taken to restore it.
Methodology: The finite element method and experimental modeling in the PASCO digital laboratory were used to determine forces in the truss rods.
Research findings: The redistribution of forces in the rods of the superstructure was detected when some of its elements are out of operation, and critical destruction is identified.
