Towards Durability of Redundant Composite Beams

The relevance of the study lies in the methodology improvement of assessing the durability of metal span structures with composite beams via the control for the stress-strain state on the basis of the system redundancy and self-organization. The variation in loads on composite beams of bridge spans during a long operation, is considered herein.Purpose: The aim of this work is to develop a methodology for estimation of durability of composite beams as self-organized systems under load.Research findings: It is shown that redundant composite beams increase their durability and technical utilization.Practical implications: Durability of composite beams with regard to the yield strength delay.
