摘要
提出了研究钢纤维混凝土受拉性能的一种新的试验方法，成功地量测出钢纤维混凝土环向受拉的应力—应变全过程曲线；应用微裂缝开展理论，对钢纤维混凝土环向受拉全过程作了宏观过程和微观机理的分析；同时利用５组１０个不同纤维情况的环状试件的试验结果，对全曲线进行了数值模拟．
This paper presents a new experimental method of making resarch on the tension of SFRC and measuring successfUlly the complete stress-strain curve with hoop tension for SFRC. With the application of the microfissure development theory, this paper also analyzes the whole procedure of the experiment of the SFRC in both way of macro-process and micro-mechanism. Meanwhile, using the test results of 10 specimens in five sets of SFRC in hoop tension, the numerical simulation is made for the complete curves.
