EFFECT OF PAVEMENT DEFECTS ON DYNAMIC PROPERTIES OF BRIDGE SPANS

The paper presents the problem of load-bearing members of bridges exposed to loads produced by heavy and ultra-heavy vehicles including pavement defects. A structural design is implemented for the identification and estimation of automated control for dynamic properties of bridge span beams accounting for corrugations. It is shown that servicing properties are changed due to non-standard vehicles. Deformation properties of bridge spans are obtained herein.

Keywords: automated control; birdbath; work load; span; stress-strain state; oscillations; composite reinforced concrete span.
