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.
