TOWARDS THE DYNAMIC BEHAVIOR OF TRUSS BRIDGE SPANS
Abstract
The paper presents a study of dynamic load testing composite reinforced concrete braced girder. The results demonstrate its performance and the stress and strain state during the dynamic property change. For the first time, such dynamic properties as attenuation and damping coefficients, eigen frequency and amplitude have been obtained for full-size braced girders that describe all stages of the behavior of the composite reinforced concrete braced girder of the bridge span. The laws of frequency properties change have been established for the braced girder operating without a roadway slab as well as with the reinforced concrete roadway slab on a metal pallet.
