Description
Summary:The paper presents the results of experimental research conducted on the newly constructed post-tensioned pre-stressed 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 to assessment of effectiveness of structural solutions applied at this bridge and establish some guidelines for using of this type of construction process in design structural solutions located over water plants in the future engineering practice. Wide range of conducted dynamic tests have allowed for comprehensive evaluation of the concrete elements effort of bridge structure. Final conclusions confirmed the observations taken from the research under static load.
