STAND TESTING FOR PREFABRICATED BEAMS USED IN THE EXECUTION OF THE SUPRASTRUCTURE OF ROAD BRIDGES

The paper presents the test on the stand of a pre-pressed concrete beam used for the execution of the overpass of roadways. The loading was carried out by means of a hydraulic installation by stepwise application of two vertical concentrate forces. Vertical beam deformations were measured with wire...

Description
Summary:The paper presents the test on the stand of a pre-pressed concrete beam used for the execution of the overpass of roadways. The loading was carried out by means of a hydraulic installation by stepwise application of two vertical concentrate forces. Vertical beam deformations were measured with wire and roller comparators, and specific deformations by electrically resistive tensometry. Are presented the obtained results and their behaviour in loading with vertical loads of pre-compacted concrete beams.
