| 摘 要： | 本文提出了用带切口梁的三点弯曲试验确定纤维增强混凝土拉伸软化本构方程的方法。通过切口染三点弯曲试验获得的载荷——加载点位移曲线可间接得到纤维增强混凝土在拉伸过程中断裂过程区的能量损耗和拉伸分离位移之间的定量关系，由此即可通过数值方法拟合出其拉伸软化本构方程。

| Abstract: | A determination method of the tensile softening constitutive equation of fiber reinforced concrete by means of three-point bend tests on notched beams is prensented. With the quantitative relation between the loss of energy and the deflection of separation in the fracture process zone during tension, the tensile softening constitutive equation can be determined by a numerical method. |
