Effectiveness of Post-tensioned Prestressed Concrete Road Bridge Realization in the Light of Research Under Dynamic Loads

The paper presents the results of experimental research conducted on the newly constructed post-tensioned prestressed concrete road bridge situated over water plant of water reservoir under dynamic field load tests in Topola village (Poland). The dynamic loads consist of four heavy trucks passing at different speeds, through threshold and braking at the midspan. The obtained results from field load tests and the calculation of dynamic coefficients, values of amplitudes of vibration velocities and frequencies of two bridge spans have allowed the assessment of the effectiveness of structural solutions applied at this bridge and the establishment of some guidelines for using of this type of construction process in design structural solutions located over water plants in the future engineering practice. The wide range of conducted dynamic tests has allowed for comprehensive evaluation of the concrete elements effort of bridge structure. Final conclusions confirmed the observations taken from the research under static load.
