Abstract:
Reviews recent research and code provisions on punching shear capacity and its relation to concrete strength. Presents the results of an experimental investigation relating punching shear to concrete strength and steel ratio. Concludes that shear capacity is proportional to the cube root of concrete strength and steel ratio and that the ACI-CSA code provisions should be reviewed.
