摘要: 在6根高强轻骨料混凝土梁、2根高强普通混凝土梁正截面受弯承载力试验的基础上,提出了轻骨料混凝土强度等级提高后的正截面受弯承载力的计算方法;在对110根轻骨料混凝土梁斜截面受剪承载力试验数据分析的基础上,提出了轻骨料混凝土强度等级提高后的斜截面受剪承载力计算公式,为《轻骨料混凝土结构技术规程》的编制提供依据。Abstract: Based on the experimental research on carrying capacity of normal section of eight reinforced high-strength concrete beams(Six were made of lightweight aggregate concrete and two were made of normal density concrete.),calculation method of carrying capacity of normal section on lightweight aggregate concrete beams was put forward.Based on the analysis on the experimental data on shear capacity of inclined section of one hundred and ten lightweight aggregate concrete beams,calculation formulae of shear capacity of inclined section on lightweight aggregate concrete beams were put forward.It presented the basis for compiling Technical Specification for Lightweight Aggregate Concrete Structures.
