摘要
讨论了钢纤维的掺入对砼受压本构关系的影响，确立了常用范围内简化的钢纤维砼受压应力－应变关系数学表达式以及相应的等效应力图形，进一步分析了钢纤维的掺入对钢筋砼受弯构件界限相对受压区高度、最大配筋率和最小配筋率的影响．
The influence of fiber on the compressive constitutive model of concrete is discussed. The simplified stress-strain relation and the equivalent stress diagram of fibre reinforced concrete are determined. The effect of fiber on the relative height of compressional zone, maximum reinforcement ratio and minimum reinforcement ratio are further analyzed.
