Based on the monotonic tensile test of grouted sleeve specimens conducted, this paper uses multifactor regression analysis to construct the equivalent constitutive relationship of grouted sleeve specimens under uniaxial tension. The study based on this constitutive relationship of grouted sleeves and the effect of bond and slip between steel and concrete were considered. The prefabricated reinforced concreted beam-column joints with grouted sleeves were presented with finite element software ABAQUS. The seismic behavior of prefabricated reinforced concreted beam-column joints with grouted sleeves under low-frequency cyclic loading was then investigated. In addition, parametric studies via finite element analysis were performed to examine the influence of various parameters on the strength and energy dissipation capacity of the specimens. The simulation results show that plastic deformation was mainly observed near the beam-column interface; the hysteretic curve of this joint was plump. The test results showed that good energy dissipation and displacement ductility capacities can be achieved. The error of yield load between the numerical simulated and experimental result was 7.11%, the error of peak load was 6.88%, the error of ultimate load was 3.76%, and the error of displacement ductility was 7.84%. Results showed that the calculated results obtained in the paper agree well with test results from the references. The finite element model adopted in this paper can reflect the seismic behavior of the prefabricated reinforced concrete beam-column joints with grouted sleeves by using equivalent constitutive relation.

带灌浆套管的预制钢筋混凝土梁柱节点有限元模型研究

本文在对灌浆套筒试件进行单调拉伸试验的基础上，采用多元回归分析方法构建了单轴拉伸下灌浆套筒试件的等效本构关系。考虑了基于灌浆套筒的这种本构关系以及钢与混凝土之间的粘结和滑移的影响的研究。用有限元软件ABAQUS介绍了带有灌浆套筒的预制钢筋混凝土梁柱节点。研究了带灌浆套管的预制钢筋混凝土梁柱节点在低频循环荷载作用下的抗震性能。此外，通过有限元分析进行参数研究，以检查各种参数对试样强度和能量耗散能力的影响。模拟结果表明，塑性变形主要发生在梁柱界面附近；这个关节的滞后曲线是丰满的。试验结果表明，可以实现良好的能量耗散和位移延展能力。数值模拟与试验结果的屈服荷载误差为7.11%，峰值荷载误差为6.88%，极限荷载误差为3.76%，位移延性误差为7.84%。结果表明，论文中得到的计算结果与参考文献的测试结果非常吻合。本文采用的有限元模型可以利用等效本构关系反映预制钢筋混凝土带灌浆套筒的梁柱节点的抗震性能。
