压浆缺陷预应力梁缩尺试验数值分析耐久性Grouting Defect Prestressed Concrete Beam Scaled Test Numerical Analysis Durability



Scaled prestressed concrete beams with duct grouting defects were immersed in chloride solu-tion, and then static loading tests are carried out on these beams. With different position of grouting defect and soaking time as variable, an attempt is made to know the laws of mid-span deflection, strain and cracking development. In the meanwhile, the corrosion of prestressed reinforcement is analyzed. In addition, in order to investigate the effect of the prestressed ten-don rupture on the bearing capacity of the voids, then based on some of the working conditions, numerical analysis of full-scale component is made to know the effect of fracture of prestressing tendon on capacity.
