本文通过试验研究,了解了二次受力钢筋混凝土迭合梁迭合面剪切破坏的基本过程及其机理,分析了迭合面抗剪强度和斜截面抗剪强度的关系,提出了设计及构造建议,经试验检验,可用于二次受力的钢筋混凝土迭合梁的迭合面抗剪设计中。

The Research on the Interface Shear Resistance of Reinforced Concrete Composite Beam in Two--stage Loading Xie Han;Wang ShengreiThrough a serial tests, this paper presented the fundamental procedu- res and mechanism of shear failure in the interface of reinforced concrete composite beam in two-stage loading, analysed the relationship between diagonal shear strength and interface shear resistance. On the basis of above analysis, this paper proposed the design and construction methods which can be used in the design of this kind of beam.Reinforced Concrete;;Composite beam;;Two-staye loading;;Shear resistance;;Mechanics test
