摘　　要：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 non elastic test of reinforced concrete, the load resistance behavior of continuous reinforced concrete T beams with deformed reinforcement was tested by modeling of microconcrete structure. The structural behaviors of these beams from loading to failure are studied. The test results including the relationships of load deformation,moment curvature and moment rotation and the process of internal force redistribution are compared with theoretical calculations,which shows that the microconcrete model test accompanied with non linear analysis and finite element analysis is an effective approach to the research for reinforced concrete theory.
