为深入研究钢筋灌浆套筒连接件的受力性能,本文提出一种基于全实体单元模型的显式动力分析方法.采用ABAQUS有限元软件建立6个钢筋灌浆套筒连接件的三维实体有限元模型进行显式动力分析,对灌浆料则分别采用混凝土的损伤塑性模型及混凝土脆性断裂模型加以模拟,并将数值分析结果与试验值进行对比,研究各试件的破坏形态、破坏过程、荷载-位移曲线等.研究表明:数值分析结果与试验值吻合良好,充分验证了有限元模型分析的可靠性,为进一步开展系统全面的参数分析及动力性能研究奠定基础.

In order to study the mechanical properties of grouted sleeve connectors,an explicit dynamic analysis method with full solid element was proposed.Six full solid model of reinforced grouted sleeve connectors were established by ABAQUS finite element software,the constitutive model of the grouting material were adopted with Concrete Damaged Plasticity model and the Brittle Cracking model respectively,and explicit dynamic analysis was used.The numerical analysis results were compared with the corresponding experimental data,the failure mode,failure process and load displacement curve of each specimen were studied.The results show that the numerical results were agree with the experimental values,and the reliability of the analysis method was verified.It also provides an method for the parameter analysis and impact performance research on reinforced grouted sleeve connectors.
