摘要:
本文对钢筋与混凝土间的握襄应力——相对滑移关系用不同方法作了试验研究,获得了弯矩、剪力共同作用下的握裹应力——滑移关系曲线。建立了模拟裂缝开展的分析模型,结构的网格可以借助于分离结点逐步变化以追踪裂缝的开展。为此编制的钢筋混凝土平面问题分析程序,考虑了材料和握裹性能的非线性特点。对于一典型梁的分析结果表明,该程序的计算结果与试验结果能较好地相符。
Abstract:
In this paper, the experimental investigation of bond-slip relation between main bars and concrete is made. The curves of bondslip relationship under the influence of both bending moments and shea forces are obtained. An analytical model is developed to simulate the crack initiation and propagation. By separating and moving the nodes, the mesh of the structure may be changed successively to follow the: crack propagaion. A computer program is set up for reinforced concrete plane stress problem, in which the nonlinear, behavior of material and bond-slip relation are taken into account. It is shown by the analysis of a typical beam tha tthe analytical results calculated by the program are in good agreement with the experimental ones.
