Bond-Slip Constitutive Model and Numerical Simulation of Shaped Steel Embedded in UHPC
-
摘要: 型钢–超高性能混凝土(UHPC)在黏结强度、变形性能等方面较型钢–普通混凝土具有明显优势,黏结滑移关系表现出独特的滑移伪塑性,而表征其黏结滑移的本构模型尚未见报道。基于既有试验数据,采用灰色关联择取关键参数拟合建立型钢-UHPC特征黏结应力及滑移量计算公式,进而提出了平均黏结应力–滑移本构模型,并经试验验证表明所提出的黏结应力计算公式和黏结滑移本构模型精度较高。在此基础上,利用界面相对损伤方程建立基于损伤滑移关系的内聚力接触模型,以考虑型钢与UHPC界面间的黏结性能并进行有限元分析。有限元与试验结果对比表明,提出的内聚力接触模型可准确模拟型钢-UHPC界面滑移及损伤发展全过程。Abstract: Shaped steel embedded UHPC (ultra-high-performance concrete) has obvious advantages over shaped steel embedded normal concrete in bond strength and deformation performance. The bond-slip relation of shaped steel embedded UHPC shows unique slip pseudo-plasticity, but the constitutive model characterizing the bond slip has not been reported. Based on the published test data, the formula to predict the characteristic bond strength and slip was developed by using the key parameters of grey correlation and a new bond stress-slip constitutive models for steel-UHPC was proposed. This study also verified the model accuracy against the published test data. Based on that, the finite element (FE) model was established to analyze the development of interface slip by using the cohesive zone model to simulate the bond-slip properties between H-shaped steel and UHPC. The comparison between the FE analysis and the test results showed that the proposed cohesive zone model could accurately simulate the slip and damage development of the shaped steel-UHPC interface.
