本文通过试验，对发生冲切破坏的钢纤维砼方板的变形性能进行了探讨．由于纤维的增强阻裂作用，板的裂缝推迟产生，裂后特性改善，破坏呈现良好延性 In this paper, through experiments, the deformation properties of steel fiber reinforced concrete square plates subjected to punching and breaking are discussed. Due to the enhanced cracking resistance of the fiber, cracks in the board are delayed, the cracking properties are improved, and the damage is in good ductility.
