| 摘 要： | 借鉴金属断裂准则，提出了轻骨料混凝土拉、压子午线和偏平面破坏包络线均为椭圆曲线的破坏准则，实现了拉、压子午线和偏平面包络线在函数类型上的完美统一，克服了二次抛物线型拉、压子午线破坏面不光滑的缺点．根据对轻骨料混凝土试验结果的拟合，量化了其拉、压子午线方程．

| Abstract: | By reference to fracture criterion of metals, elliptical curves are brought forward for tensile and compressive meridians of lightweight aggregate concrete failure criterion. Tensile and compressive meridians and failure envelope in deviated plane of lightweight aggregate concrete were faultlessly integrated in that they both were elliptical curves. The unsmooth disadvantage of tensile and compressive meridians due to adoption of quadratic parabola is overcome. Failure equations are quantified for lightweight aggregate concrete regressed on experimental data. |
