摘要
通过试验，对钢纤维配筋混凝土方板的冲切性能进行了探讨．由于钢纤维的增强阻裂作用，板的斜裂缝推迟产生，裂后特性改善，破坏呈现良好延性。
Based on the tests,investigations of the deformation and strength characteristics of steel fiber reinforced concrete square slabs subjected to punching shear are presented. The steel fibers not only enhanced the ultimate punching shear 1oads, but also transformed brittle type punching shear failures into gradual and ductile failures,and all the deflections , rotations,steel strains and concrete strains are decreased at equivalent loads.
