Mechanical performance of improved PHC pile-to-pile cap connection

  • 摘要: 进行了配置非预应力筋、桩身混凝土中掺入钢纤维以及桩端缠CFRP三种改进的PHC管桩与承台连接处桩端的往复荷载试验,研究了构件的滞回性能、耗能性能和刚度退化等。试验结果表明,桩身混凝土掺入钢纤维之后,管桩的耗能性能有所改善,三种改进方式对管桩的刚度都有一定的提高,其中配置非预应力筋的效果最为显著。采用有限元分析软件ABAQUS对节点在往复荷载作用下的受力性能进行了模拟分析,计算结果和试验结果吻合较好;在此基础上,对试件各进行了全过程受力分析,结果表明,管桩改进之后,预应力筋的应力有所减小。
    Abstract: The prestressed high strength concrete piles were reinforced with non-prestressed steel bar (PRC pile), reinforced with steel fiber concrete pile (SFPHC), or confined with CFRP, respectively in this paper. The improved PHC pile-to-pile cap connections were tested to study the hysteretic behavior, energy dissipation and rigidity degeneration. The test results show that steel fiber can improve the energy dissipation, as a result, the rigidities of the three types of PHC piles are increased, especially the PRC piles. The finite element software ABAQUS was used to simulate the nonlinear behavior of pile-cap connections under monotonic load. The comparison between analytical and experimental results shows that the proposed modeling technique is capable of accurately describing the behavior of the connections. On this basis, a full loading history analysis was carried out, and it is found that the stresses of prestressed bars are reduced.
