RC 伸臂梁采用 PVA-ECC 加固抗剪试验研究
Shear Behavior of RC Overhanging Beams Strengthened with PVA-ECC
摘要
Abstract
Based on the experimental research on the shear test behavior of two general beams and two overhanging RC beams strengthened with PVA-ECC,the regulations for the change of the mode of diago-nal cracks,failure,deflection and strain have been analyzed in the experiment.The results show that this reinforced method can increase the crack-resisiting capacity and impove the shear stiffness and the load-bearing capacity of the beam.According to the test results,the computational formula of the shear load ca-pacity of overhanging RC beams strengthened with PVA-ECC was established.The calculated results fit well with the experimental results,thus providing a theoretical reference for practical engineering designs.关键词
