| Abstract: | The paper studies the punch-shear damage mechanism of reinforced concrete slabs. The advanced measuring component used inside the concrete is adopted in experiment, and the concrete deformation along the inclined punch-shear damage surface is measured. The concrete strain distribution, the crack formation and its development rule on the damage surface are summarized.The similarity and difference between the normal concrete and the pumic lightweight aggregate concrete slabs about the punch-shear damage are compared. Finally, the semiexperimental, semitheoretical calculation formula of punch-shear bearing capacity is estaiblished. |
