摘要
在分析试验资料的基础上，应用应力变分法建立了钢筋混凝土梁在集中荷载作用下钢筋与混凝土间的粘结滑移模型．该模型既能圆满地满足边界条件，又综合考虑了材料特性、保护层厚度等因素的影响及粘结滑移关系沿钢筋位置的变化，且与试验结果符合较好，为研究钢筋混凝土构件的刚度、变形和裂缝宽度及应用有限单元法分析钢筋混凝土结构的非线性性能提供了一个较实用的模型．
Based on the experimental data,a stress variation model of the bond stress-slip relationshipbetween steel bar and concrete is proposed. The characteristic of the model is that the boundaryconditions are satisfied very well; the effects of the properties of materials, the concrete cover,the crack spacing and distance away from the cracked cross section are considered. Goodcorrespondence between measured and calculated bond stress-slip relationships is found.Thismodel is useful to study the stiffness , deformation and crack width of R.C. members, and tononlinear analysis of R.C. structures by the finite element method.
