Experimental Investigation on Flexural Behavior of Prestressed Concrete-Filled Steel Box Beam

  • An experiment was conducted on 8 prestressed concrete-filled steel box beams to investigate the flexural behavior of prestressed concrete-filled steel box beams.The test parameters include concrete strength,steel strength,prestressing degree,steel ratio and loading pattern.The strain distribution of steel and concrete and the stress increment of prestressed tendons were obtained.The effect of local buckling of steel plate on the flexural behavior of prestressed concrete-filled steel box beams was investigated.By considering the confined effect of compression core concrete,load-deflection curves were gained with the fiber analysis method.The predicted results based on the fiber analysis method were compared with the experimental ones to show an accordance.The research results show that prestressed concrete-filled steel box beams have a good flexural behavior to have a vast application prospect.
