[摘要]详细介绍了钢筋混凝土非线性有限元分析中剪力传递系数η的意义及其在有限元分析中的作用。在总结一些学者提出的取值建议之后,深入分析了决定剪力传递系数取值的因素。最后针对两个不同类型的试验,进行了非线性有限元数值模拟,将在选取各种剪力传递系数的情况下所得到的数值结果与试验结果对比。在以上分析与总结的基础之上提出了在非线性有限元分析中,剪力传递系数的选取原则。

Abstract:The shear retention factor and its function in nonlinear finite element analysis(FEA) are introduced. The values or models of the shear retention factor suggested by former scholar are collected and further the factors that affect the shear retention factor are analyzed. At last, two experiments are simulated by FEA software MSC.Marc and then the analysis results are compared to the experiment, so the affections of the shear retention factor to the analysis results are discovered. Based on all above, some suggestions for the selection of the shear retention factor are given.
Keywords:shear retention factor; reinforced concrete; nonlinear FEA; experiment
