DESTRUCTIVE TESTING OF TWENTY-YEAR-OLD PRESTRESSED CONCRETE BRIDGE BEAMS IN FREEZING-THAWING REGION
The paper conducted a destructive test and nonlinear finite element analysisfor four pieces of pre-stressed concrete hollow plate,which have served for 20 years in the freezing-thawing region. The results showedthattypical bending destruction occurred in the test beams under the action of bending load, and the bearing capacity of the test beams decreased by a littlecompared with finite element analysis results. The test beams showed typical bending response before the reinforcement yieldedunder the action of uniform load,andthe pre-stressed reinforcement in the bending-shearing zone slippedafter reinforcement yielded, the final ultimate bearing capacity of the test beam was only 75% of the finite element calculation value
