Analysis of Existing Concrete Bridges Material properties.
Material properties are important input data to the load-carrying capacity determination.
In the case of concrete bridges, it is needed to specify material properties of concrete, reinforcement and prestressing steel.
In cases, where the consequential distribution of internal forces and stresses in the existing concrete is affected by the inhomogeneity, respectively time factor is affecting properties of concrete, it is necessary to take into account the impact of the construction process and load history to determine the actual response of the structure.
To determine deformations, the mean values of material properties are considered and the effects of shrinkage and creep and the impact of cracks should be taken into account.
