摘要

摘要: 纤维增强混凝土(FRC)具有受拉应变-硬化和多裂缝开展特性,替代普通混凝土作为梁柱节点核心区基体材料以减少箍筋的数量。该文通过建立协调方程、平衡方程和本构关系,对FRC梁柱节点在地震作用下的受力性能进行分析,提出FRC梁柱节点核心区剪应力-剪应变骨架曲线理论计算模型,并研究其开裂点、屈服点和峰值点的剪应力和剪应变计算方法。将理论计算结果与试验结果进行比较,结果表明:提出的剪应力-剪应变理论计算模型可以较好地反映FRC梁柱节点在地震作用下的剪应力-剪应变关系。

Abstract: The fiber-reinforced concrete(FRC) is characterized with a tensile strain-hardening behavior and numerous micro-cracks development. In order to reduce the amounts of stirrups, the FRC was used in the core of a beam-column joint. The compatibility equation, equilibrium equation and constitutive laws were established to analyze the force behavior of an FRC beam-column joint due to earthquake. A shear stress-strain skeleton curve model was presented, and the calculation method of shear stress and shear strain of crack point, yield point and peak point were studied. The comparison between theoretical calculation results and experimental results shows that the proposed model for shear stress-strain calculation is in a good agreement with the shear stress-strain relationship of an FRC beam-column joint under earthquakes.
