Analysis the Influence of Non-Prestressed Reinforcement for Horizontal Bearing Capacity of PHC Pipe Pile

Abstract:

We analyze the configuration of the non-pretressed reinforcement impact on the level of bearing capacity of PHC piles to effectively solve the poor performance of the general bending of pretressed concrete pile,using ANSYS finite element analysis software,through configurating the pretressed concrete pile with appropriate amount of ordinary non-presressed reinforcement.The results of numerical calculation show that the performance of PHC pile bending has been greatly improved and the deflection and bending when cracking were significantly better than ordinary PHC pile with the confiuration of non-prestressed reinforcement. We also analyze the effect of non-prestressed reinforcement and prestressing steel when the concrete piles cracking,datd shows that prestressing steel reached stress yielding firstly.The results provide a theoretical basis of the application of precast piles in the foudation ditch support project.
