摘要
本文通过九根压弯构件的破坏性能试验，对劲性钢筋轻骨料混凝土压弯构件的破坏形式、截面应变、轴村比对延性的影响等力学性能做以研究．证明了平截面假定．确定了破坏准则．绘出了不同轴压比的压弯构件的滞回曲线．为以后对劲性钢筋轻骨料混凝土结构的进一步研究，提供了有益的资料。
Based on destructive tests of nine compression-bending members of steel reinforced lightweight concrete, the poper researches the form of destructive,sttains of cross-section, effection of ductility by axial compression-ratio and so on. The paper proves flat section-assumtion,gbes the standard of destructive and claws the held-up curve.The research offers the useful information for further studies about steel reinforced lightweight concrete.
