| 摘 要： | 基于FEAPpv有限元分析平台,采用分离式模型,自定义一个粘结-滑移滞回模型,模拟二维钢筋混凝土构件中锚固钢筋的粘结-滑移性能;自定义模型以滕智明等的滞回规则为基础,参考了Eligehausen等关于锚固钢筋在反复荷载作用下粘结-滑移滞回关系的试验结果,修改了滕智明等的模型滞回路径中某些控制点的取值;对端部反复加载的锚固钢筋进行分析,验证本文粘结-滑移滞回模型模拟锚固钢筋和混凝土界面性能的有效性。结果表明:该模型能有效反映锚固长度对钢筋加载端力-位移曲线的影响。

| Abstract: | A new bond-slip hysteretic model was presented and nested in the FEAPpv finite element analysis platform which was used in the discrete model to simulate bond-slip behavior of anchored rebar in two-dimensional reinforced concrete members.The new model was based on the hysteretic model presented by Teng Zhi-ming,et al,but some parameters in the model were calibrated by the cyclic testing results of bond-slip hysteretic relationships under reversed cyclic loading obtained by Eligehausen,et al.The efficiency o... |
