| 摘 要： | 新颁布的GB 50010—2010《混凝土结构设计规范》中提出了一种钢筋混凝土黏结滑移本构关系,为了充分探讨其适用性,利用DIANA软件分别建立了考虑和不考虑黏结滑移关系的两类数值模型,并就梁的开裂荷载、荷载-挠度曲线、裂缝分布形态等方面对仿真与试验结果进行了比对分析。结果表明:在各方面采用新规范黏结滑移本构关系的分析结果均优于不考虑黏结滑移关系时的情形,该本构关系能够较好地反映钢筋混凝土之间的协同工作性能,有利于提高钢筋混凝土结构数值分析的精度。

APPLICABILITY ANALYSIS OF BOND-SLIP CONSTITUTIVE RELATIONSHIP IN THE NEW CODE FOR DESIGN OF CONCRETE STRUCTURES |
| |
| Abstract: | Newly issued "Concrete Structural Design Code"(GB 50010—2010) proposes a bond-slip constitutive relation between steel bars and concrete.In order to fully explore its applicability,two types of numerical models considering and not considering the bond-slip relationship were established by the software DIANA.Based on which,the cracking loads,the load-deflection curves,the crack distribution patterns of the beams were compared and analyzed between simulation and experimental results.It is shown that the analysis results with the bond-slip constitutive relation are better than that not considering the bond-slip relationship.The bond-slip constitutive relation proposed by the new code can better reflect the coordinated working performance between concrete and steel,and can help improve the accuracy of numerical analysis. |
