基于钢筋混凝土模型试验理论 ,对配变形钢筋 T形截面连续梁的受力性能进行了微混凝土模型试验 ,研究了模型梁从开始加载到破坏各个阶段的结构性能 ,分析比较了模型和理论分析计算的荷载—挠度关系、塑性内力重分布过程以及弯矩—曲率关系等 ,结果表明微混凝土模型试验是钢筋混凝土理论研究的一种有效途径。
Based on the theory of RC model test, the micro-concrete model test of the T-shaped continuous beam with deformed deformed bars was carried out. The structural performance of the model beam from the initial loading to the failure stage was studied. The model and theoretical analysis were compared Load-deflection relationship, plastic internal force redistribution process and moment-curvature relationship. The results show that the micro-concrete model test is an effective way to study the theory of reinforced concrete.
