Determination of the Stress Concentration Coefficient in the Anchor’s Area of Composite Span Structures of the Road Bridges
Journal Title: Металлические конструкции - Year 2017, Vol 23, Issue 2
Abstract
The article presents the results of analysis of the tensely-deformed state of a five-span steel-reinforced concrete structure of a road bridge, made on a beam unbroken circuit. The calculation is performed in the LIRA computational complex under the elastic work of materials on the action of shearing and tearing forces. The main purpose of the work was to determine the coefficient of stress concentration in the zone of rigid stops for concrete slabs of the roadway. For this purpose, a section of a plate with a metal beam and unifying elements was modeled, broken down into small volumetric and lamellar bodies. This allowed us to analyze in detail the nature of the distribution of normal stresses along the height and length of the span structure. The obtained coefficient can be used when calculating the existing designs for endurance and strength, and also when determining the residual life of bridge structures to predict their service life.
