钢筋混凝土结构粘结滑移关系的应力函数法

Stress Function Method for Bond Stress-Slip Relationship Between Steel Bar and Concrete

通过分析试验资料,应用应力函数建立了钢筋混凝土梁在载荷作用下纯弯段钢筋与混凝土粘结应力与滑移量之间的关系,考虑了材料的非线性、混凝土的厚度、裂缝间距、材料的弹性模量等因素的影响,且与试验结果符合较好.

Based on the experimental data, an elastoplastic method for bond stress-slip relationship between steel bar and concrete of reinforced concrete beams under loading,is proposed. The method has considered the effects of the properties of materials, the concrete cover thickness and the crack intervals. Good correspondence between measured and calculated bond stress-slip relationship is found .
