| Abstract: | The deformation distributing and the load-deflection characteristic of steel fiber high-strength concrete square slab subjected to punching shear are provided according to the tests. As a matter of convenience, usable formulas for calculating the deformation of punching shear slab before failure are presented. The comparison shows good agreement between the calculating values and the testing curves. |
