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 of the new model was justified, by means of anchored rebar with reversed cyclic loading on the loading tip, to simulate bond behavior at the interface between concrete and anchored rebar. The model can satisfactorily simulate effect of anchored length on force-displacement curve at the loading tip of the rebar.
